POWERVR OpenVG SupportPOWERVR OpenVG Support• POWERVR MBX

- Designed for Khronos OpenGL ES 1.1- 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


• 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

OpenVG QualityOpenVG Quality

• 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

No Anti-Aliasing Faster Anti-Aliasing Better Anti-Aliasing


Golden Rules for Maximum PerformanceGolden 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
