3 What is IWAYAG? IWAYAG is a graphics accelerator dedicated for vector graphics, consisting of -Hardware IP core to be incorporated to the customer s SoC -OpenVG driver IWAYAG design and features -Native OpenVG accelerator -Architecture of IWAYAG is based on the OpenVG pipeline stage design -Path generation to Blending/Antialias stages are implemented by hardware -No CPU tessellation. Fill is done by hardware using outline buffer -Hardware bezeir rasterizer -Extensive cache control mechanism for fast filling -Support fast FSAA Implemented by Hardware 3 NEC System Technologies, Ltd. 2008
4 Why IWAYAG? Requirements from the consumer devices market -Flash support -Many consumer device manufacturers plan to incorporate richer UI -Flash support is a MUST to efficiently develop the rich UI -Smooth playback of Flash contents while using low-end CPUs -Cost and/or battery power limits CPU selection -100Mhz CPU without FPU is common for Digital cameras. -Long battery life -Flash acceleration by 3D engine consumes too much battery powers Native OpenVG graphics accelerators best meet the requirements -Good Flash performance while using low-end CPUs -Much lower power and die size than 3D engine 4 NEC System Technologies, Ltd. 2008
5 Total Solution of IWAYAG Supporting software - OpenVG1.1 Driver - FlashLite Vector font and drivers Supporting menu - Porting to customer s LSI - Customization of IWAYAG hardware - Application Design - Board Design/Manufacturing Application Design Services Board Design/Manufacturing Services IWAYAG Porting/Customization Services Outline font, drivers FlashLite Player Database Browser Middleware Other Middleware Products Hardware Driver IWAYAG Graphics IP 5 NEC System Technologies, Ltd. 2008
