SIGGRAPH August 10th 2015 – Los Angeles, CA –The Khronos Group, an open consortium of leading hardware and software companies, today announced it is launching a new Safety Critical working group to develop open graphics and compute acceleration standards for markets that require system safety certification. Khronos previously developed the OpenGL® SC 1.0 specification that defined a safety critical subset of OpenGL ES 1.0. The new working group will adapt more recent Khronos standards including OpenGL ES with programmable shaders, and the new generation Vulkan™ API for high-efficiency graphics and compute. Work on detailed proposals is already underway, and companies interested to participate are welcome to join Khronos for a voice and a vote in the development process. More information on Khronos safety critical specifications and activities is available at: https://www.khronos.org/safetycritical.
“Visual computing acceleration will be a vital component of many emerging safety critical market opportunities including Advanced Driver Assistance Systems (ADAS), autonomous vehicles and new generation avionics systems,” said Neil Trevett, president of the Khronos Group and vice president at NVIDIA. “The new Safety Critical working group will build on the experience of shipping OpenGL SC, but now can adapt the latest open standards in the Khronos ecosystem for markets with demanding system certification requirements.”
The new Safety Critical working group is an evolution of the OpenGL ES Safety Critical Working Group that released the OpenGL SC 1.0 specification in 2005 with a fixed function graphics pipeline, with minor updates to OpenGL SC 1.0.1 in 2009. The working group will use DO-178C Level A / EASA ED-12C Level A as the safety critical benchmark for the avionics industry and ISO 26262 certifability to satisfy the safety critical requirements of the automotive industry. The working group is also working to align its specifications with the Future Airborne Capability Environment (FACE™) consortium (www.opengroup.us/face) technical standard for graphics.
“Codeplay is excited to be contributing in this evolution of Khronos standards for safety critical solutions,” says Andrew Richards, CEO of Codeplay. “We are strongly involved in Khronos standards and the safety critical working groups will enable computer vision systems to prevent car accidents and save lives.”
“The development of a next generation Khronos graphics standard for safety critical systems is an important step to advance avionics, automotive, and other high reliability display systems,” says Steve Viggers, vice president of software at CoreAVI.
“KNU fully supports Khronos developing new graphics and computing API standards for safety critical applications,” says Nakhoon Baek, professor of Kyungpook National University. “We expect that these new standard APIs will be widely used in safety-related applications by enabling the appropriate software quality certification process for each industry segment. As an academic organization, KNU will work to develop training programs, applications, tools and solutions using these new standard APIs.”
“Next generation automotive solutions call for advanced vision, rendering and compute capabilities in a high reliability system. Texas Instruments is focused on making cars safer and smarter through technology innovations and is excited to be participating in definition of Khronos standards for Safety Critical systems,” says Anand Balagopalakrishnan, architect, automotive graphics at Texas Instruments.

Khronos Expands Scope of 3D Open Standard Ecosystem
New generation Vulkan graphics and compute API supported by Android;
OpenGL ES 3.2 specification embraces AEP functionality for mobile;
Cutting edge desktop 3D hardware enabled with new OpenGL extensions
SIGGRAPH August 10th 2015 – Los Angeles, CA –The Khronos Group, an open consortium of leading hardware and software companies, today announced significantly expanded scope and momentum for its family of open standard 3D graphics APIs. Vulkan™, the new generation API for high-efficiency access to graphics and compute on modern GPUs, is on track for implementation and specifications later this year. It has received support from Android, SteamOS, Tizen, and multiple Linux distributions, including Ubuntu and Red Hat. The new OpenGL® ES 3.2 specification absorbs AEP (Android Extension Pack) functionality to enhance pervasive graphics capabilities across mobile, consumer, and automotive devices. A set of OpenGL extensions will also expose the very latest capabilities of desktop hardware. More information on all Khronos specifications is available at: https://www.khronos.org.
Vulkan gives applications direct control over GPU acceleration for maximized performance and predictability, and uses Khronos’ new SPIR-V™ intermediate language specification for shading language flexibility. Vulkan minimizes driver overhead and enables multi-threaded performance on mobile, desktop, console, and embedded platforms. In parallel with finalizing the Vulkan specification, Khronos is working to drive an in-depth Vulkan ecosystem to:
- Reach out to key non-Khronos developers for feedback during specification drafting;
- Construct an open source Vulkan conformance test suite leveraging and merging with the Android Open Source Project (AOSP) drawElements Quality Program (dEQP) framework to enable direct feedback and contributions from developers to resolve cross-vendor inconsistencies;
- Develop a Vulkan tools architecture that can load code validation, debugging and profiling layers during development, without impacting production performance. The first open source, cross-vendor Vulkan SDK is being developed by Valve working with LunarG;
- Build key SPIR-V tools in open source, including translators from GLSL, OpenCL C and C++, a validator to check the correctness of any SPIR-V file and a SPIR-V assembler/disassembler.
“Hardware and software companies need an open 3D API to maximize market reach and minimize porting costs, and Vulkan is being forged by a broad consortium of industry leaders to do exactly that,” said Neil Trevett, president of the Khronos Group. “Vulkan’s adoption and availability on platforms such as Android, Windows, Linux and SteamOS will ensure strong developer support - creating a wealth of high-quality content and applications for any platform that leverages this royalty-free standard.”
About OpenGL ES 3.2
The new OpenGL ES 3.2 and OpenGL ES Shading Language 3.20 specifications bring AEP, plus additional functionality, into core OpenGL ES. AEP is a set of OpenGL ES extensions announced last year to bring console-class gaming to Android. OpenGL ES 3.2 will drive the pervasive availability of advanced desktop-class graphics functionality on a large class of mobile, consumer and automotive hardware, and will be adopted by Android. OpenGL ES 3.2 capabilities include:
- Geometry and tessellation shaders to efficiently process complex scenes on the GPU;
- Floating point render targets for increased flexibility in higher precision compute operations;
- ASTC compression to reduce the memory footprint and bandwidth used to process textures;
- Enhanced blending for sophisticated compositing and handling of multiple color attachments;
- Advanced texture targets such as texture buffers, multisample 2D array and cube map arrays;
- Debug and robustness features for easier code development and secure execution.
About OpenGL Extensions
The OpenGL extensions released today expose cutting-edge desktop graphics capabilities and pave the way for new versions of OpenGL when this functionality is pervasively available, including:
- Streamlined sparse texture functionality to more effectively manage multisample sparse textures and uncommitted and unpopulated texture areas;
- Enhanced shader functionality including interlocks to efficiently ensure proper execution order for multi-pass algorithms, 64-bit integer handling, control of coverage results in sample masks for early fragment testing, enhanced atomic counter capabilities and a 64-bit monotonically incrementing counter to derive local timing information;
- Control over the number of threads used to compile shaders to accelerate compilation time;
- Modifiable locations of samples within a pixel to increase multisample antialiasing quality;
Lastly, the OpenGL ES 3.2 compatibility extension enables the use of desktop OpenGL to develop mobile applications.
“AMD is thrilled to see the adoption this low-level, high-performance graphics API into an industry standard such as Vulkan” said Raja Koduri, corporate vice president, engineering, AMD. “At AMD, we strive to deliver maximum performance and control into the talented hands of game and graphics application developers everywhere and we see Vulkan as an excellent step in that direction.”
“As a founding member of Khronos, ARM is fully supportive of the latest specification of open standard 3D graphics APIs,” said Jem Davies, vice president of technology, media processing group, ARM. “As the number of graphical devices in everyday life continues to grow, the new OpenGL ES and Vulkan APIs are important steps in enabling game and application developers to provide richer and more energy-efficient user experiences.”
“Intel is excited to be part of the continued rapid development of graphics APIs like Vulkan and OpenGL ES 3.2 and to showcase these APIs running on our hardware at SIGGRAPH 2015,” said Aaron Coday, director of visual computing engineering, Intel. “We can't wait to see what application developers can do with the new features and performance benefits they offer on Intel Architecture.”
“Imagination is proud to contribute to the continued development of Khronos APIs for mobile graphics.

Khronos Releases Standardized Data Format Specification
Precise standalone format descriptions enable extensible communication of data between standards and applications
Portland, OR – July 29th 2015 – The Khronos Group today announced the ratification and public release of the Khronos Data Format Specification 1.0. This new standard provides precise mechanisms to generate machine-readable format descriptions of repetitive data, such as pixels, enabling standards and software to cleanly communicate and interoperate. This royalty-free specification will be used across multiple Khronos API initiatives, and is open to be used by third party standards and applications. The Khronos Data Format Specification and additional information is available at: https://www.khronos.org/dataformat.
“The minefield of data formats and their interpretation by each API is one of the most challenging areas of integration of device components, and interoperation between them,” said Alon Or-bach, chair of the EGL Working Group. “The Khronos Data Format Specification provides a clean and complete descriptor to describe all common formats and enables APIs to define clear mappings to them. This will improve life for device integrators, and be an invaluable tool for applications that depend on data flowing between different hardware blocks, such as computer vision and augmented reality.”
Today, many standards use proprietary enumerated data descriptions that are not extensible, and are often incompletely specified, resulting in data conversion errors and incompatibilities. By using a descriptive data format, software can flexibly and reliably use a large number of possible formats without specifically coding for each one. The Khronos Data Format Specification supports versioning and extensions, as well as storing common data interpretation details to avoid the need for separate metadata.
This specification has already been used to describe precise descriptions for Vulkan™ and OpenVX™ internal data formats. APIs can also define extensions with data format descriptors to be used for both interoperation between multiple standards and for describing user-visible data.
Working Group Member Quotes
“The Khronos Data Format Specification simplifies sharing data between APIs, improving the efficiency of complex applications,” said James Jones, senior software engineer at NVIDIA. “As a world leader in visual computing, NVIDIA supports the adoption of precisely defined data formats in both Khronos and third-party standards.”
“To stay at the cutting edge of the industry both in graphics and multimedia, Samsung combines many software and hardware technologies from different sources inside and outside of the company,” said Steve Gi-Byoung Park, managing director of Samsung R&D Institute UK. “The Khronos Data Format Specification offers a consistent and unambiguous way to describe and interpret buffers, images and textures, reducing the development effort in integrating these components and improving the time-to-market of Samsung’s innovations.”

Industry Momentum Building for OpenVX Computer Vision Acceleration API
Production and open source sample implementations shipping;
Specification update available; OpenVX tutorial at CVPR 2015
June 4th 2015 – The Khronos Group today announced the ratification and public release of the OpenVX™ 1.0.1 specification, a maintenance update to the open, royalty-free standard for cross platform acceleration of computer vision applications. OpenVX 1.0.1 integrates bug fixes and clarifications resulting from feedback from working group members and the wider industry implementing and using the specification. OpenVX enables performance and power-optimized computer vision processing, especially important in embedded and real-time uses cases such as face, body and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more. In addition to the OpenVX conformance tests and Adopters Program launched in late 2014, Khronos is now shipping an open source, fully-conformant CPU-based implementation of OpenVX 1.0 that runs on Linux, Android or Windows. The full OpenVX 1.0.1 specification and details about the sample implementation are available at www.khronos.org/openvx.
OpenVX at CVPR2015
Members of the OpenVX working group are organizing an OpenVX tutorial at the CVPR 2015 conference in Boston that will be held in the afternoon of June 7th. The tutorial will discuss when vision developers might choose to use OpenVX, OpenCV or OpenCL™, and provide an introduction to OpenVX by mapping example computational photography and driver assistance algorithms to the OpenVX graph API. The second half of the tutorial will be a practice session, solving a computer vision problem using the OpenVX sample implementation, followed by a chance for attendees to write their own OpenVX sample code and chat with OpenVX experts. More information on the OpenVX tutorial is here.
OpenVX defines a higher level of abstraction for execution and memory models than compute frameworks such as OpenCL, enabling significant implementation innovation and efficient execution on a wide range of architectures while maintaining a consistent vision acceleration API for application portability. An OpenVX developer expresses a connected graph of vision nodes that an implementer can execute and optimize through a wide variety of techniques such as: acceleration on CPUs, GPUs, DSPs or dedicated hardware, compiler optimizations, node coalescing, and tiled execution to keep sections of processed images in local memories. This architectural agility enables OpenVX applications on a diversity of systems optimized for different levels of power and performance, including very battery-sensitive, vision-enabled, wearable displays. The precisely defined specification and conformance tests for OpenVX make it ideal for deployment in production systems where cross-vendor consistency and reliability are essential.
OpenVX 1.0 has been finalized for just a few months, but already production implementations are beginning to ship into the market including the recently announced OpenVX-capable IP core by Vivante

Khronos Releases SYCL 1.2 Final Specification
C++ single-source heterogeneous programming for OpenCL 1.2
May 11th 2015, IWOCL, Stanford University, CA – The Khronos™ Group,an open consortium of leading hardware and software companies, today announced the ratification and public release of the finalized SYCL ™ 1.2 specification. SYCL for OpenCL™ enables code for heterogeneous processors to be written in a “single-source” style using completely standard C++. The multi-vendor SYCL 1.2 standard is available royalty-free for industry use, and the full specification together with details about the SYCL conformance test suite and Adopters Program can be found at www.khronos.org/sycl.
SYCL single-source programming enables host and kernel code to be contained in the same source file, using the same templates for both, with full OpenCL acceleration. Developers can program at a higher level than OpenCL C, but always have access to existing code through seamless integration with OpenCL programs, C/C++ libraries and frameworks such as OpenMP. SYCL includes templates and lambda functions for higher-level application software that can be cleanly coded for optimized acceleration across the extensive range of shipping OpenCL 1.2 implementations.
“SYCL is complementary to the ongoing evolution of the OpenCL kernel language and we see the lessons and technologies from SYCL and the evolving OpenCL C++ kernel language merging and influencing each other over time,” said Andrew Richards, chair of the SYCL working group and CEO of Codeplay. “C++ programing techniques can help provide performance portability for OpenCL applications by providing highly adaptive parallel software than is easily used and re-used.”
OpenCL’s interop capability is inherited by SYCL to enable applications to use SYCL in conjunction with OpenGL, DirectX and the upcoming Vulkan API without memory-copy overhead. In return, SYCL can provide simplified error handling and effective compute and communication overlap between host and devices.
SYCL 1.2 can be implemented to work with a variety of existing and new C++ compilers and layers over OpenCL 1.2 implementations from diverse vendors. SYCL 1.2 builds on the features of C++11, with additional support for C++14 and also will enable C++17 Parallel STL programs to be accelerated on OpenCL devices in the future. SYCL 1.2 also builds on the Khronos SPIR™ 1.2 portable binary format and fully leverages the ongoing work at the OpenCL and SPIR working groups at Khronos with the aim to provide long-term support for future OpenCL capabilities, including OpenCL 2.1 and SPIR-V™.
The C++ standards body is working on a new Parallel STL standard for C++17. To support this effort, Khronos is kick-starting an open-source project to support Parallel STL on top of SYCL, running on OpenCL devices.This project is hosted at https://github.com/KhronosGroup/SyclParallelSTL.
See SYCL at IWOCL 2015
Khronos is pleased to have a notable profile at IWOCL 2015, the 3rd International Workshop on OpenCL. IWOCL is a community led meeting of OpenCL developers, researchers and suppliers to share OpenCL best practice and to advance the OpenCL standard. More information on IWOCL, including how to register, can be found at www.iwocl.org. Khronos SYCL sessions are as follows:

- May 13 12:10PM: SYCL working group chair Andrew Richards will be presenting on SYCL 1.2.
Industry Support for SYCL
“It is great to see innovation in higher-level programming languages that tap into the tremendous compute power of OpenCL capable devices” says Greg Stoner, senior director at AMD. “Providing developers with a single-source C++ programming model that runs across multiple vendor devices showcases the potential that an open compute standard can deliver. We look forward to seeing this trend continue to unfold in the future.”
“At Codeplay, we believe software developers benefit from working with open standards because it gives them the greatest flexibility to deploy their software to their customers,” said Maria Rovatsou, Principal Software Engineer, SYCL technologies, Codeplay. “At the same time, we recognize that users are demanding ever higher-performance software and longer battery lifetimes on devices that are available everywhere. We worked hard to fulfill this challenge to give C++ developers the full power and performance of OpenCL via the SYCL open standard.”
“At Imagination, we are committed to helping drive standards around heterogeneous processing and GPU compute. We’re delighted to see SYCL running on PowerVR GPUs, extending the power and efficiency of GPU accelerated computing to a greater number of mobile apps developers” said Peter McGuinness, director of Multimedia Technology Marketing, Imagination Technologies.”
“Qualcomm Technologies, Inc. worked with Khronos on the specification of SYCL 1.2 in order to help enable mobile developers to utilize C++ for programming OpenCL-supporting GPUs,” said Eric Demers, vice president of GPU hardware at Qualcomm Technologies, Inc. “SYCL 1.2 has the potential to enable the development of portable libraries that abstract away the host/device boundary, delivering the necessary flexibility to use higher-level C++ abstractions in mobile devices that use Snapdragon™ processors.”
"SYCL is the open standard, higher-level programming model the heterogeneous computing community has been waiting years for. SYCL tracks the latest developments in modern C++, with a clear path to C++ 17 to simplify parallel programming across multiple platforms. What I find unique about SYCL is the broad range application domains it is suitable for: allowing simple accelerator programming for beginner programmers by using only modern C++, but also enables power programmers to use advanced features to reach the ultimate performance while keeping an elegant software architecture," said Ronan Keryell, lead developer of triSYCL, the Open Source SYCL implementation project.

About OpenCL 2.1
The OpenCL C++ kernel language is a static subset of C++14 and significantly boosts parallel programming productivity by providing lambda functions, classes, templates, operator overloading, and many other C++ features to free developers from low-level coding details without sacrificing performance. OpenCL C++ enables reusable device libraries and containers for easily sharable code that is fast and elegant, and templates enables meta-programming for highly adaptive software that cleanly delivers performance portability.
In another significant announcement today, OpenCL 2.1 and Vulkan™, the new open standard API for high-efficiency access to graphics and compute on modern GPUs, are now sharing core intermediate language technologies resulting in SPIR-V; a revolution in the Khronos Standard Portable Intermediate Representation initially used by OpenCL™, now fully defined by Khronos with native support for shader and kernel features. SPIR-V splits the compiler chain, enabling high-level language front-ends to emit programs in a standardized intermediate form to be ingested by Vulkan or OpenCL drivers. Eliminating the need for a built-in high-level language source compiler significantly reduces driver complexity and will enable a diversity of language front-ends. Additionally, a standardized IR provides a measure of kernel IP protection, accelerated kernel load times and enables developers to use a common language front-end, improving kernel reliability and portability across multiple implementations.
In addition to the introduction of the OpenCL C++ shading language, OpenCL 2.1 brings enhancements to the OpenCL API, including:
- Subgroups, that expose hardware threading, are bought into core, together with additional subgroup query operations for increased flexibility;
- clCloneKernel enables copying of kernel objects and state for safe implementation of copy constructors in wrapper classes;
- Low-latency device timer queries support alignment of profiling between device and host code.
“OpenCL 2.1 has responded to developer demand with a C++ based kernel language which delivers the next level of programmer productivity in parallel programming, while still preserving backwards compatibility for existing OpenCL C kernels,” said Neil Trevett, president of the Khronos Group and chair of the OpenCL working group and vice president at NVIDIA. “The use of SPIR-V by Vulkan and OpenCL will fundamentally reshape the graphics and compute ecosystem by enabling diverse language and middleware front-ends to leverage the hardware community’s investment in optimized back-end drivers. Khronos is investigating catalyzing the OpenCL 2.1 ecosystem with an open source front-end OpenCL C++ compiler implementation and a convertor between SPIR-V and LLVM, and we welcome developer feedback on this and any other aspect of OpenCL 2.1.”
Industry Support for OpenCL 2.1
“AMD is excited to see OpenCL™ evolve to include a C++ kernel language, which will significantly expand the number of developers targeting heterogeneous platforms,” said Manju Hegde, corporate vice president, Heterogeneous Applications and Developer Solutions, AMD. “We also applaud the bold move to SPIR-V which provides a common binary target language across graphics and compute. This greatly simplifies vendor driver development and enables innovation in new languages targeting cross-platform acceleration of applications.”
“Mobile devices are now the primary computing platform for consumers,” said Dennis Laudick, vice president, partner marketing, media processing group, ARM. “As a founding member of Khronos, ARM is fully behind the new OpenCL specification including new features that enable mobile computing to be more energy-efficient.”
“Intel has been deeply involved in the development of OpenCL 2.1. We’re excited to get this new specification into the hands of Intel platform developers,” said Jon Khazam, vice president and general manager of Intel’s Visual & Parallel Computing Group. “The addition of C++ support and movement toward a Common IR across OpenCL and the new Vulkan graphics API will facilitate wider adoption and deployment of OpenCL in heterogeneous computing applications.”
“The addition of the C++ kernel language in OpenCL 2.1 is a very exciting development for the HPC community,” said Simon McIntosh-Smith, head of the HPC research group at the University of Bristol. “C++ is being increasingly used to develop scientific codes, and so this development will make it much easier to port new HPC software to a wide variety of high performance, parallel hardware. OpenCL 2.1’s C++ kernel language could cause a step change in the rate of adoption for OpenCL in HPC.”
“We at YetiWare believe that software should run as fast as possible by using all of the processors on a system, and the OpenCL standard makes that possible,” said AJ Guillon, founder and chief technical officer, YetiWare Inc. “The OpenCL C++ kernel language and SPIR-V are both major advancements and big wins for developers.”

Khronos Finalizes and Releases OpenVX 1.0 Specification for Computer Vision Acceleration
Fast, portable, power-efficient vision processing across diverse hardware architectures; Full conformance test suite and Adopters Program immediately available;
Khronos to ship open source OpenVX implementation by end 2014
October 20th, 2014, – The Khronos™ Group today announced the ratification and public release of the finalized OpenVX™ 1.0 specification, an open, royalty-free standard for cross platform acceleration of computer vision applications. OpenVX enables performance and power-optimized computer vision processing, especially important in embedded and real-time uses cases such as face, body and gesture tracking, smart video surveillance, advanced driver assistance systems (ADAS), object and scene reconstruction, augmented reality, visual inspection, robotics and more. In addition to the OpenVX specification, Khronos has developed a full set of conformance tests and an Adopters Program, that enables implementers to test their implementations and use the OpenVX trademark if conformant. Khronos plans to ship an open source, fully-conformant CPU-based implementation of OpenVX 1.0 before the end of 2014. The full OpenVX 1.0 specification and details about the OpenVX Adopters Program are available at www.khronos.org/openvx.
OpenVX defines a higher level of abstraction for execution and memory models than compute frameworks such as OpenCL™, enabling significant implementation innovation and efficient execution on a wide range of architectures while maintaining a consistent vision acceleration API for application portability. An OpenVX developer expresses a connected graph of vision nodes that an implementer can execute and optimize through a wide variety of techniques such as: acceleration on CPUs, GPUs, DSPs or dedicated hardware, compiler optimizations, node coalescing, and tiled execution to keep sections of processed images in local memories. This architectural agility enables OpenVX applications on a diversity of systems optimized for different levels of power and performance, including very battery-sensitive, vision-enabled, wearable displays.
“Increasingly powerful and efficient processors and image sensors are enabling engineers to incorporate visual intelligence into a wide range of systems and applications,” said Jeff Bier, founder of the Embedded Vision Alliance. “A key challenge for engineers is efficiently mapping complex algorithms onto the processor best suited to the application. OpenVX is an important step towards easing this challenge.”
The precisely defined specification and conformance tests for OpenVX make it ideal for deployment in production systems, where cross-vendor consistency and reliability are essential. OpenVX is complementary to the popular OpenCV open source vision library that is also used for application prototyping but is not so tightly defined and lacks OpenVX graph optimizations. Khronos has defined the VXU™ utility library to enable developers to call individual OpenVX nodes as standalone functions for efficient code migration from traditional vision libraries such as OpenCV. Finally, as any Khronos specification, OpenVX is extensible to enable nodes to be defined and deployed to meet customer needs, ahead of being integrated into the core specification.
“AMD is an enthusiastic advocate for natural user interfaces enabled by computer vision,” said Greg Stoner, senior director of application engineering, Heterogeneous Applications and Solutions, AMD. “As a proponent of open standards and a provider of highly-parallelized architectures ideal for computer vision, we embrace the OpenVX standard and look forward to standardized proliferation of these experiences throughout the industry.”
“OpenVX will be a great tool for future development of computer vision applications,” said Johan Paulsson, CTO at Axis Communications. “We see excellent potential for making development efforts future-proof by separating algorithms from hardware.”
“Cadence is integrating OpenVX into our Tensilica® Imaging/Vision Library software development kit to enable higher performance and power optimization for our scalable and configurable IVP-EP DSP cores, which are widely adopted for imaging, computer vision and automotive drivers’ assistance applications,” stated Dr. Chris Rowen, CTO of the IP Group, Cadence.
“CEVA applauds the Khronos Group on achieving this important milestone with the release of OpenVX specification,” said Eran Briman, vice president of marketing at CEVA. “With an extensive list of vendors currently sampling their computer vision ICs based on the CEVA-MM3101 DSP and a growing developers community, it is clear that the optimal way to meet the stringent performance and power requirements of computer vision applications is to offload CV processing to a dedicated processor. OpenVX enables this for developers in a seamless manner and we are now integrating it into our CEVA-MM3101 Application Developers Kit (ADK).”
“As one of the first innovators in embedded vision, CogniVue will be supporting a compliant OpenVX implementation for our APEX Image Cognition Processing technology with announcements coming,” said Tom Wilson vice president of product management and marketing at CogniVue.
“We see OpenVX as a promising tailor-made standard tool for developing performant, low-power, while portable computer vision applications for our mobile devices,” said Zhouhong, president of
Central Hardware Engineering Institute, Huawei. “Based on its tightly defined nature, we also see
OpenVX to serve as a standard benchmark suite which can promote the development of ever-more power efficient computer vision accelerators, a component likely to become must-have for coming mobile products.”
“Vision applications will be a defining feature and differentiator for products in a wide range of markets including mobile, smart home, automotive, retail analytics, public safety and more. Imagination’s IP cores including PowerVR GPUs and video processors, Raptor imaging processors and MIPS CPUs are already used in vision applications, and we expect this trend to accelerate,” said Peter McGuinness, director of Multimedia Technology Marketing, Imagination. “We are delighted to be involved with defining the specification for OpenVX 1.0, which we believe is a valuable starting point for accelerating creation and adoption of vision applications.”
“Intel supports and welcomes the adoption of OpenVX as an important element in proliferating computer vision usage models,” said Ofri Wechsler, Intel Fellow. “In fact, Intel has a long history in supporting the development of the computer vision domain spanning the creation of OpenCV more than two decades ago to the active optimization of OpenCV 3.0 for Intel CPUs and Intel Processor Graphics”
“OpenVX enables disrupting computer vision applications that run on low-power mobile and wearable devices,” said Victor Erukhimov, CEO of Itseez, Inc., and chair of the OpenVX working group. “We see it as an optimization layer for many of our projects, from sophisticated middleware for smartphones to advanced driver assistance technologies and mobile 3D scanning.”
“We are excited to contribute to the next generation of computer vision applications,” says A.G.K. Karunakaran, CEO of MulticoreWare. “Our experts are already working with leading device OEMs and semiconductor companies on the development of OpenVX platforms and computer vision libraries that leverage multicore heterogeneous processors including CPUs, GPUs, DSPs, VSPs, and other programmable architectures.”
“Real-time vision processing combined with advanced graphics is inter-twining the real and virtual worlds to enable true visual computing applications,” said Neil Trevett, president of the Khronos Group and vice president of mobile ecosystem at NVIDIA. “NVIDIA is integrating OpenVX into our VisionWorks SDK so GPU-accelerated vision nodes can be easily combined into pipelines for a range of advanced vision applications.”
"Renesas is pleased to take part in the launch of OpenVX that is expected to have a significant impact on the vision application domain," said Masayuki Mizuno, vice president, chief of Incubation Center at Renesas Electronics Corporation. "We believe OpenVX will break new ground in vision applications by introducing graph-based optimization as well as by defining standard vision APIs.”
“Samsung is committed to bringing novel, useful, and fun computer vision applications to our mobile devices. The standard framework of OpenVX lets us develop portable applications for diverse application processors and consumer devices, from tablets and handsets to wearables,” said Mike Polley, senior vice president and head of the Samsung Mobile Processor Innovation Lab. “Samsung encourages the industry to support OpenVX to enable broad availability of computer vision on mobile platforms, allowing Samsung and independent software developers to unlock the potential of our advanced processing architectures and deploy pervasive, revolutionary and efficient computer vision in power-constrained environments.”
