IPU, VPU and GPU

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相關

VPU：跟視訊播放相關，主要包括HW codec和視訊後處理等

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）相關
