MPEG-4 Video Compression Encoder
"The AllianceCORE MPEG-4 Video Compression Encoder from 4i2i is a fully pipelined dedicated video compression engine capable of supporting several popular video standards. The core reads a video frame from memory and outputs an encoded bit stream (and decoded reference picture) back to memory. Host processor requirements are minimal and only 7 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 and capture components with no loss of performance.
