Arm releases PerfDoc v1.0

• Tags: Vulkan Blog

/assets/uploads/news/news_graphics/PerfDoc_Release2.2.png

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.

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.
