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
