A look at the PowerVR graphics architecture: Deferred rendering

In my previous article, I wrote about how our GPU architecture works. It’s a novel architecture which works unlike any other, and we call it a tile-based deferred renderer, or TBDR. The basic premises are simple enough in concept. First, we split the screen up into tiles to

PowerVR Series7XT Plus GPUs: where advanced graphics meets computer vision

About a month before CES 2015 I wrote an in-depth blog article about our PowerVR Series7XT GPUs, presenting the industry-leading performance efficiency gains made since Series6XT and giving an overview of their desktop-class features. Today I’m very excited to announce GT7200 Plus and GT7400 Plus, two new GPUs

Measuring GPU compute performance

After exploring a quick guide to writing OpenCL kernels for PowerVR Rogue GPUs and analyzing a heterogeneous compute case study focused on image convolution filtering, I am going to spend some time looking at how developers can measure the performance of their OpenCL kernels on PowerVR Rogue GPUs.

Supported zero-copy flows inside the PowerVR Imaging Framework

In a previous article we described our PowerVR Imaging Framework, a set of extensions to the OpenCL and EGL APIs that enable efficient zero-copy sharing of memory between a PowerVR GPU and other system components such as a CPU, ISP and VDE. Most flows use EGL to facilitate

The PowerVR Imaging Framework camera demo

Writing and optimizing code for heterogeneous computing can be difficult, especially if you are starting from scratch. Imagination has set up a new page where developers can access the source code for an example camera and video post-processing application that leverages the PowerVR Imaging Framework to implement efficient

Heterogeneous compute case study: image convolution filtering

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

The PowerVR Imaging Framework for Android

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
