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

IWAYAG is a graphics accelerator dedicated for vector graphics, consisting of

-Hardware IP core to be incorporated to the customer’s SoC

-OpenVG driver

What is IWAYAG?

Implemented by Hardware


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

Evaluation Environment of the IWAYAG performance

IWAYAG has been designed to run at 200MHz clock.In this evaluation, due to the design of the evaluation board, the testing has been conducted with

IWAYAG operating at 48MHz clock.
