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
