Press Releases

The Khronos Group, an open consortium of leading hardware and software companies, today announced the ratification and public release of the OpenCL™ 2.1 and SPIR-V™ 1.0 specifications for heterogeneous parallel computation. Consumption of the new SPIR-V cross-API intermediate language is guaranteed in the core OpenCL 2.1 specification. Khronos has released open source utilities and extensions to enable use of SPIR-V in OpenCL 1.2 and 2.0, as well as the upcoming Vulkan™ graphics API, ensuring widespread availability of its powerful runtime capabilities for developers of parallel computation languages and frameworks. The OpenCL C++ kernel language released in the OpenCL 2.1 provisional specification is being finalized and will be released imminently, also using SPIR-V for run-time execution.

The Khronos Group, an open consortium of leading hardware and software companies, today announced that the glTF™ 1.0 (GL Transmission Format ) royalty-free specification for transmission and loading of 3D content has been finalized for Ratification and is immediately available for use by tools and application vendors. glTF is an efficient, interoperable asset delivery format that compresses the size of 3D scenes and models, and minimizes runtime processing by applications using WebGL™ and other APIs. glTF also defines a common publishing format for 3D content tools and services.

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.

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™ Group today announced the ratification and public release of updated OpenCL™ 2.0 and Provisional SYCL™ 1.2 specifications. The new specifications integrate feedback from the developer community, align with the latest C++ developments, and increase implementation consistency for improved portability of heterogeneous parallel applications. The latest OpenCL and SYCL specifications are open, royalty-free and available online.

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 Khronos™ Group today announced the ratification and public release of the SPIR™ 2.0 provisional specification that provides a non-source encoding, and binary level portability, for OpenCL™ 2.0 device programs.  SPIR (Standard Portable Intermediate Representation) is the industry's first open, cross-platform Intermediate Representation standard for portable heterogeneous parallel computing and is based on LLVM IR. SPIR enables developers to avoid exposing sensitive kernel source and enables a diversity of language front-ends to easily target OpenCL platforms and devices in addition to OpenCL C.

The Khronos™ Group, an open consortium of leading hardware and software companies, today announced growing industry support for the OpenGL® family of 3D standards that are advancing the visual experience for more than two billion mobile devices and PCs sold each year. OpenGL, OpenGL ES™ and WebGL™ are the world’s most widely deployed APIs that between them provide portable access to graphics and compute capabilities across multiple platforms, including Android, iOS, Linux, OS X, Windows and the Web.

The Khronos™ Group today in an earlier press conference announced a number of new and significant updates to its portfolio of open, royalty free industry standards that enable the authoring and acceleration of parallel computing, graphics, vision, sensor processing and dynamic media on a wide variety of platforms and devices:

  • OpenGL® ES 3.1 Specification Released – The next leap in mobile & embedded graphics
  • WebCL™ 1.0 Specification Released – Browser-based heterogeneous compute acceleration
  • SYCL™ 1.2 Provisional Specification Released – Enabling high-level C++ tools for OpenCL
  • OpenCL™ 2.0 Adopters Program Launched – Driving OpenCL 2.0 conformance
  • EGL™ 1.5 Specification Released – The essential glue for secure, integrated API rendering

The Khronos™ Group today announced the ratification and release of the EGL™ 1.5 specification. EGL is an open, royalty-free standard that defines a portable interface to underlying operating system and display platforms to handle graphics context management, surface and buffer binding, and rendering synchronization. EGL also provides interop capability to enable efficient transfer of data and events between Khronos APIs. The new EGL 1.5 specification incorporates functionality for enhanced rendering flexibility and security, improved interop between OpenGL® or OpenGL ES™ and OpenCL™ for mixed compute and rendering acceleration, and standardized support for multiple common operating systems including Android and 64-bit platforms.
