Modern mobile application processors are highly heterogeneous, combing a variety of different hardware components optimized for different tasks. As shown in the figure below, a processor designed for vision might include an Image Signal Processor (ISP) for acquiring image sensor data, a vector processor such as a GPU for efficient data-parallel operation on pixels and feature vectors, and a CPU … Continued

Computer vision is the use of computers to extract useful meaning from images, such as those that arise from photographs, video and real-time camera feeds. Thanks to the proliferation of low-power parallel processors, the increasing availability of 3D sensors and an active ecosystem of algorithm developers, it is now possible for many embedded devices to analyse their environments on-demand or … Continued

In a previously published article, I offered a quick guide to writing OpenCL kernels for PowerVR Rogue GPUs; this sets the scene for what follows next: a practical case study that analyzes image convolution kernels written using OpenCL. Many image processing tasks such as blurring, sharpening and edge detection can be implemented by means of a convolution between an image … Continued

In my previous article about heterogeneous architectures, I identified memory bandwidth as the main bottleneck for implementing power-efficient algorithms for computer vision. Luckily, Imagination has created an innovative solution designed to address this common issue in mobile and embedded devices – and it comes in the form of the PowerVR Imaging Framework. Introducing the PowerVR Imaging Framework The PowerVR Imaging … Continued

A few months back I reported on the MIPS-based Mongoose-V chip guiding the New Horizons probe in its quest to reach Pluto. The story captured the headlines of many publications and generated many questions about the MIPS architecture (more on this in a separate article). Today I’d like to focus on another important space mission called Hayabusa-2 that is currently … Continued

Virtualization, security and trusted execution environments are all trending topics in the new age of ubiquitous connectivity. However, there is a lot of confusion over how these technologies work together and their role in the overall mobile and embedded computing ecosystem. Luckily, Mike Borza, CTO of the Synopsys-owned Elliptic Technologies has published an extremely insightful whitepaper that clarifies how secure virtualization … Continued

In an article published earlier this week, I described how developers can implement fast, ray traced soft shadows in a game engine running on our PowerVR Wizard architecture. Today I’d like to present some very exciting results which demonstrate how ray tracing delivers significant reductions in memory bandwidth and power consumption over traditional rasterized methods (i.e. cascaded shadow maps).
