Learn more about the Virtual Reality Standard Initiative Exploratory Group Overview Press Release Vulkan - Industry Forged Vulkan is a new generation graphics and compute API that provides high-efficiency, cross-platform access to modern GPUs used in a wide variety of devices from PCs and consoles to mobile phones and embedded platforms. Khronos launched the Vulkan 1.0 specification on February 16th, 2016 and Khronos members released Vulkan drivers and SDKs on the same day. Everything you need to come up to speed on Vulkan and to forge ahead and explore whether Vulkan is right for your engine or application is now available on the official Vulkan homepage . API Overview Press Release Vulkan 1.0 Specification Overview Presentation Feedback Forum NNEF - Industry Call for Participation in a new neural network initiative Neural network technology has seen recent explosive progress in solving pattern matching tasks in computer vision such as object recognition, face identification, image search, image to text, and is also playing a key part in enabling driver assistance and autonomous driving systems. Convolutional Neural Networks (CNN) are computationally expensive, and so many companies are actively developing mobile and embedded processor architectures to accelerate neural net-based inferencing at high speed and low power. As a result of such rapid progress, the market for embedded neural net processing is in danger of fragmenting, creating barriers for developers seeking to configure and accelerate inferencing engines across multiple platforms.

It is incomplete and subject to change. The draft specification and related converters and loaders are available on github . Overview Overview slide deck glTF Project glTF on Github SPIR - Standard Portable Intermediate Representation SPIR is a family of languages including: • SPIR-V, the first open standard intermediate language for parallel compute and graphics, and • SPIR 1.2 and SPIR 2.0 for OpenCL C programming, mapping onto LLVM IR. SPIR is a portable, non-source representation for devices programs. It enables application developers to avoid shipping kernel source and to manage the proliferation of de vices and drivers from multiple vendors. SPIR enables the consumption of code from third party compiler front-ends for alternative languages.
