IP Description: 

"The AllianceCORE MPEG-4 Video Compression Decoder from 4i2i is a fully pipelined dedicated video compression decoder engine capable of supporting several popular video standards. The core reads an input bit stream (and reference picture) from memory and outputs a decoded picture back to memory. Host processor requirements are minimal and only 6 registers (specifying the frame locations and coding options) need be programmed once at the beginning of each frame. The core requires a single memory component preferably clocked at the same speed as the core itself.The core can generally share this memory with the host or render components with no loss of performance.
