5 Copyright Khronos Group, Page 5 POWERVR OpenVG Support POWERVR MBX - Designed for Khronos OpenGL ES OpenVG is a new API that maps well on to the existing POWERVR MBX Core - ~90% of API Hardware Accelerated - Highly optimised industry-leading Tessellation Code - Extensive usage of caching within the driver - Impressive performance achieved up to 4x 2GHz Pentium Software renderer - Issues with OpenVG mapping onto OpenGL ES 1.1 hardware: - 100% conformance means not all functions map well onto an OpenGL ES 1.1 pipeline - Other ~10% of functionality falls back to Software Rendering - Synchronisation between CPU and GPU introduces serious performance hit - Conformance test requirements makes fast-paths impossible - Some Software-based Setup Support required - Triangle Based OpenGL ES Hardware means Curved Paths need to be tessellated POWERVR SGX - Programmable multi-threaded shader-based multimedia GPU - General Purpose Graphics Processor - Designed with OpenGL ES 2.0+ and OpenVG 1.1 in mind - 100% Acceleration of the API

6 Copyright Khronos Group, Page 6 OpenVG Performance Hardware Accelerated OpenVG offers considerable benefits - Higher Performance - Higher Image Quality - Lower Power Consumption POWERVR SGX will achieve significantly higher OpenVG performance - at equivalent clock speed Comparison with an optimised commercially available OpenVG software implementations

7 Copyright Khronos Group, Page 7 OpenVG Quality No Anti-Aliasing Faster Anti-Aliasing Better Anti-Aliasing Anti-Aliasing Algorithms make a big difference to the perceived image quality - Increased Detail - Smooth Edges - Reduced crawling effects along edges with animation POWERVR MBX and SGX offer a wide range of AA Modes matching customer requirements

8 Golden Rules for Maximum Performance Avoid very large paths - Keep in mind system resource limitations of Handheld Platforms - Large paths require a lot of memory and are more expensive to Tessellate - Optimise your Paths and consider splitting large paths into simpler smaller paths Cache the tessellation of your paths - Introduce a warm-up phase where paths are drawn at their maximum used scale Avoid modifying paints, masks or paths regularly - Might force a re-tessellation of your paths and can cause stuttering performance - Similar to modifying or creating new texture data mid-scene in OpenGL ES Use batching to reduce API calls - API Calls always have CPU Overhead, minimise the number of calls using batching Do not change anti-aliasing mode mid-frame - Most hardware only supports Full Screen Anti-Aliasing not per primitive - Might force multiple renders and compositing operations Do not use vgreadpixels() in a real application - Forces a CPU/GPU synchronisation resulting in lost performance but OK for screenshots Release all the Path, Paint and Image data if your application is done with it Copyright Khronos Group, Page 8
