Video graphics system[IPU, VPU and GPU]

IPU: Image Processing Unit
• – Display
• – Camera
• – Image Rotation, Inversion, Color Space Conversion
• – Image quality enhancement
• – Video/graphics combining

VPU: Video Processing Unit
• – Video encoding & decoding
• – Post-filtering
• – Rotation & inversion

GPU: Graphics Processing Units
• – 2D (OpenVG 1.1)
• – 3D (OpenGL ES 2.0)

IPU：跟Camera，Display相关

VPU：跟视频播放相关，主要包括HW codec和视频后处理等

VPU is a high performance multi-standard video codec IP that can perform the H.264 BP/MP/HP, VC-1 SP/MP/AP, MPEG-4 SP/ASP, Divx, MPEG-1/2, RV-8/9/10, and MJPEG decoding and encoding.

GPU：跟2D（OpenVG）和3D（OpenGL）相关
