VCODEC

VCODEC is composed of video decoder and video encoder. VCODEC is connected to VCODEC_AHB bus through an AHB slave and VCODEC_AXI through an AXI master.

Video decoder and video encoder share many internal memories and they also share the bus master and slave interfaces. So it prevents video decoder and video encoder from working simultaneously. Encoding and decoding now have to time-share the memory resource on a frame by frame basis.

Video decoder and encoder share the Memory Management Unit (MMU) and AXI bus. Video decoder can support cache-able bus operation.
