PerfDoc is a Vulkan layer which aims to validate applications against the Mali Application Developer Best Practices Guide. Just like the LunarG validation layers, this layer tracks your application and attempts to find API usage which is discouraged. PerfDoc focuses on checks which can be done up-front, and checks which can portably run on all platforms which support Vulkan. The intended use of PerfDoc is to be used during development to catch potential performance issues early. The layer will run on any Vulkan implementation, so Mali-related optimizations can be found even when doing bringup on desktop platforms. Just like Vulkan validation layers, errors are reported either through VK_EXT_debug_report to the application as callbacks, or via console/logcat if enabled. Dynamic checking (i.e. profiling) of how an application is behaving in run-time is not currently in the scope of PerfDoc. Some heuristics in PerfDoc are based on "arbitrary limits" in case where there is no obvious limit to use. These values can be tweaked later via config files if needed. Some checks which are CPU intensive (index scanning for example), can also be disabled by the config file. Please visit the GitHub repository for PerfDoc.
Intel has released their Graphics Driver 15.46 to provide launch support, as well as bugfixes, feature updates, Computer Vision and AI application development support, and support for Windows 10 Creator’s Update features. The driver is only for Windows 10 64-bit. Intel has enabled additional OpenCL media extensions, as well as a few preview extensions. In addition, 15.46 brings support for OpenGL v4.5, Vulkan v1.0.38, and programmable sample positions in Direct3D12.
Apple announced several updates to the Mac lineup earlier this month at WWDC. Geekbench 4, which includes a new GPU Compute Benchmark that measures the performance of GPUs at performing compute tasks, shows that GPU performance with OpenCL has improved considerably with an increase of up to 80% when compared to the equivalent 2015 model. If you’re interested in how your computer compares you can download Geekbench 4. Find the complete benchmark results on the Geekbench website.
Imagination Technologies announces the first GPU IP core based on its new PowerVR Furian architecture, the Series8XT GT8525. Says Tatiana Solokhina, CTO, RnD Center ELVEES, a Khronos member: “As a provider of SoCs for a wide range of global video analytics applications, we require a GPU that offers the best compute performance in a power constrained footprint. The new PowerVR Furian 8XT family from Imagination provides us an industry-leading GPU with new ALU for increased performance density and efficiency. In addition, support for standard compute APIs such as OpenVX enables easy implementation of real world vision processing applications.” Furian is designed to address the increasing compute requirements across multiple applications and market segments with efficient use of compute APIs including OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1.
Nvidia released version 3.6 of the GeForce companion tool Experience. In addition to optimizing the graphics settings of all the supported games installed on your system, this update adds gameplay recording and broadcasting support for OpenGL and Vulkan games.

VeriSilicon Holdings Co., Ltd. announces VIP8000, a highly scalable and programmable processor for computer vision and artificial intelligence. It delivers over 3 Tera MACs per second, with power consumption more efficient than 1.5 GMAC/second/mW and the smallest silicon area in industry with 16FF process technology. The VIP8000 can directly import neural networks generated by popular deep learning frameworks, such as Caffe and TensorFlow and neural networks can be integrated to other computer vision functions using the OpenVX framework. The processor is programmed by OpenCL or OpenVX with a unified programming model across the hardware units, including customer application-specific hardware acceleration units. Learn more about the VIP8000.
This week at the Embedded Vision Summit (EVS) in California Imagination is showcasing their latest Convolutional Neural Network (CNN) object recognition demo. All of these networks have been implemented using Imagination’s own DNN library. IMG DNN sits on top of OpenCL but doesn’t obscure it, and makes use of OpenCL constructs so it can be used alongside other custom OpenCL code. Imagination’s Paul Brasnett is talking at EVS on the subject of ‘Training CNNs for Efficient Inference‘ and for further reading, take a look at this CNN based number recognition demo, which uses OpenVX with CNN extension. Learn more about Imagination's Convolutional Neural Networks.
AMD announced a dual-GPU graphics card designed for professionals: the Polaris-architecture-based Radeon Pro Duo. Built on the capabilities of the Radeon Pro WX 7100, the Radeon Pro Duo professional graphics card is designed to excel at media and entertainment, broadcast, and design and manufacturing workflows, delivering outstanding performance and superior flexibility that today’s creative professionals demand. The new GPU supports OpenCL 2.0, OpenGL 4.5 and Vulkan 1.0.
Cadence Design Systems, Inc. announced that the Cadence Tensilica Vision P-Series DSPs are the first imaging/vision DSPs to pass Khronos Group's conformance tests for the OpenVX 1.1 specification. Application developers can now take advantage of Tensilica Vision P5/P6 functionality without detailed knowledge of the hardware architecture and still achieve high performance. This enables faster development of computer vision and imaging applications on Tensilica Vision P-Series DSPs being deployed in applications processors for mobile, automotive, drone, security, augmented reality/virtual reality (AR/VR) and other markets. Read the full press release.
Furian is designed to address the increasing compute requirements across multiple applications and market segments with efficient use of compute APIs including OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1*. Furian adds a bi-directional GPU/CPU coherent interface for efficient sharing of data; and a transition to user mode queues from kernel mode queues which reduces latency and CPU utilization for compute operations. Based on a published Khronos specification, GPUs based on the PowerVR Furian architecture are expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
