Imagination Releases PowerVR CLDNN Neural Network SDK and Image for Acer Chromebook R13

Last month, Imagination Technology released their PowerVR CLDNN SDK, an AI-oriented API that leverages OpenCL support in PowerVR GX6250 GPU in order to  create network layers for constructing and running a neural network on PowerVR hardware. Eventually the SDK will support PowerVR Series2NX Neural Network Accelerator, but while waiting for the hardware, the company has provided a firmware that runs only on Mediatek MT8173 based Acer Chromebook R13. The SDK includes a demo taking a live camera feed to identify the object(s) the camera is pointing at, using known network models such as AlexNet, GoogLeNet, VGG-16, or SqueezeNet. All models are Caffe models trained against the ImageNet dataset, a benchmark function is included within the demo. Beside simply playing with the demos, you’ll be able to study the source code to check out various helper functions such as file loading, dynamic library initialisation and OpenCL context management, and read documentation such as the PowerVR CLDNN reference […]

Imagination PowerVR Series8XT GT8540 GPU Can Drive up to Six 4K Screens, Supports Hardware Virtualization

Imagination Technologies introduces PowerVR Furian architecture last year with improved performance, power and density, as well as dual cluster PowerVR Series8XT GT8525 GPU based on the new architecture, and targeting high-end smartphones, virtual reality and automotive products. The company has now introduced a quad cluster Furian GPU called PowerVR Series8XT GT8540 that can simultaneously drive up to six 4K screens at 60fps thanks to an 80% fillrate density improvement, and supports virtualization providing separation of services and applications. The new GPU mostly targets the automotive market with some new cars now requiring multiple screen support with high resolution displays for cluster, Head-Up Display (HUD) and infotainment. Hardware virtualization is equally important for automotive application, as you’ll want to separate safety-critical code, from infotainment applications for example, so if the latter crashes, the safety-critical code can still run unhindered. Each would run on separate shaders processing unit, with up to 8 […]

Synaptics Introduces VideoSmart BG5CT 4K HDR Multimedia Video Processor for Set-Top Boxes

Marvell used to design Media SoCs running Android TV such as ARMADA 1500 Ultra (aka BG4CT). That part of Marvell business has very recently been sold to Synaptics, which has just unveiled VideoSmart BG5CT multimedia SoC with 4K “Advanced” HDR video processing for the set-top-box market. The BG5CT is said to be pin-to-pin compatible with BG4CT Android TV SoC, features a quad core ARM CPU @ 1.6 GHz with 15K DMIPS, an Imagination PowerVR Series8XE GE8310 GPU, and a security engine enabling secure boot, Trusted Rendering Path, full TrustZone, and video watermarking carrier-grade security making it suitable for Pay TV operators and set-top-box manufacturers. Synaptics’ Qdeo video processing technology adds 4K “Advanced HDR” – including HDR10, HLG, Dolby Vision, and Technicolor HDR, among user video processing technology. The company did not provide that many details, but BG5CT appears to mostly add HDR support compared to BG4CT, and replace Vivante GC7000 GPU by […]

Imagination Announces PowerVR Series2NX Neural Network Accelerator (NNA), and PowerVR Series9XE and 9XM GPUs

Imagination Technologies has just made two announcements: one for their PowerVR Series2NX neural network accelerator, and the other for the new high-end GPU families: PowerVR Series9XE and 9XM. PowerVR Series2NX neural network accelerator The companies claims 2NX can deliver twice the performance and half the bandwidth of nearest competitor, and it’s the first dedicated hardware solution with flexible bit-depth support from 16-bit down to 4-bit. Key benefits of their solution (based on market data available in August 2017 from a variety of sources) include: Highest inference/mW IP cores to deliver the lowest power consumption Highest inference/mm2 IP cores to enable the most cost-effective solutions Lowest bandwidth solution with support for fully flexible bit depth for weights and data including low bandwidth modes down to 4-bit 2048 MACs/cycle in a single core, with the ability to go to higher levels with multi core The PowerVR 2NX NNA is expected to be […]

Imagination PowerVR “Furian” Series8XT GT8525 GPU Targets High-end Smartphones, Virtual Reality and Automotive Products

Imagination Technologies has unveiled their first GPU based on PowerVR Furian architecture with Series8XT GT8525 GPU equipped with two clusters and designed for SoCs going to into products such as high-end smartphones and tablets, mid-range dedicated VR and AR devices, and mid- to high-end automotive infotainment and ADAS systems. The Furian architecture is said to allow for improvements in performance density, GPU efficiency, and system efficiency, features a new 32-wide ALU cluster design, and can be manufactured using sub-14nm (e.g. 7nm process once available). PowerVR GT8525 GPU supports compute APIs such as OpenCL 2.0, Vulkan 1.0 and OpenVX 1.1. Compared to the previous Series7XT GPU family, Series8XT GT8525 GPU delivers 80% higher fps in Trex benchmark, an extra 50% fps in GFXbench Manhattan benchmark, 50% higher fps in Antutu, doubles the fillrate throughput for GUI, and increases GFLOPs for compute applications by over 50%. GT8525 GPU is available for licensing […]

Imagination PowerVR G6230 is the First GPU To Pass Khronos OpenVX 1.1 Conformance

The Khronos Group is the non-profit consortium group behind open standards and APIs for graphics, media and parallel computation such as OpenGL for 3D graphics, OpenCL for GPGPU, OpenVG for 2D vector graphics, etc… OpenVX is one of their most recent open, royalty-free standard, and targets power optimized acceleration of computer vision applications 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. The first revision of the standard was released in 2014, and the latest OpenVX 1.1 revision was just released in May 2016. We’ve already seen OpenVX 1.1 support in Nvidia Jetson TX1 module & board, but Khronos has a conformance program to test  implementations, and if successful, allow companies to use the logo and name of the API. The version first GPU to pass OpenVX 1.1 conformance is Imagination Technologies PowerVR […]
