VeriSilicon’s Vivante VIP8000 Neural Network Processor with OpenVX and OpenCL

• Tags: OpenCL OpenVX

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.

Object recognition using Convolutional Neural Networks on a PowerVR GPU

• Tags: OpenCL OpenVX

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.

Imagination’s Furian GPU a massive step up in performance with OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1

• Tags: GPU Conformance Vulkan OpenCL OpenVX VR

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.

Igalia contributions to Intel OpenGL 4.5 certified drivers

• Tags: Conformance OpenGL

Igalia has contributed several features and bugfixes that helped achieve this important milestone. During the last several months, Igalia has been working hard on improving the Intel driver to enable 64-bit floating point support. We developed OpenGL extensions such as ARB_gpu_shader_fp64 and ARB_vertex_attrib_64bit, which were a major contributor to increasing the supported OpenGL version. As members of the Khronos Group, Igalia also had the opportunity to contribute tests and bugfixes to the conformance suite itself.

NVIDIA 378.66 drivers for Windows offer OpenCL 2.0 evaluation support

• Tags: windows drivers OpenCL

NVIDIA graphics driver for Windows version 378.66 is now offering some OpenCL 2.0 support. From the release notes: "New features in OpenCL 2.0 are available in the driver for evaluation purposes only." Some known issues include: The current implementation is limited to 64-bit platforms only; OpenCL 2.0 allows kernels to be enqueued with global_work_size larger than the compute capability of the NVIDIA GPU. The current implementation supports only combinations of global_work_size and local_work_size that are within the compute capability of the NVIDIA GPU; For executing kernels (whether from the host or the device), OpenCL 2.0 supports non-uniform ND-ranges where global_work_size does not need to be divisible by the local_work_size. This capability is not yet supported in the NVIDIA driver, and therefore not supported for device side kernel enqueues.
