1.2.10 Graphics Engine

 3D Graphics Engine :

 High performance OpenGL ES1.1 and 2.0, OpenVG1.1 etc.

 Embedded 4shader cores with shared hierarchical tiler

 Separate vertex(geometry) and fragment(pixel) processing for maximum parallel

throughput

 Provide MMU and L2 Cache with 32KB size

 Triangle rate : 30M triangles/s

 Pixel rate: 300 pixels/s @ 150MHz

 2D Graphics Engine(RGA module) :

 Pixel rate: 300M pixel/s without scale, 150M pixel/s with bilinear scale, 66.5M

pixel/s with bicubic scale.

 Bit Blit with Strength Blit, Simple Blit and Filter Blit

 Color fill with gradient fill, and pattern fill

 Line drawing with anti-aliasing and specified width

 High-performance stretch and shrink

 Monochrome expansion for text rendering

 ROP2, ROP3, ROP4 full alpha blending and transparency

 Alpha blending modes including Java 2 Porter-Duff compositing blending rules ,

chroma key, and pattern mask

 8K x 8K raster 2D coordinate system

 Arbitrary degrees rotation with anti-aliasing on every 2D primitive

 Programmable bicubic filter to support image scaling

 Blending, scaling and rotation are supported in one pass for stretch blit
