System Architecture of H.264/AVC Codec LSI for Digital HD Camcorder

A single chip H.264/AVC codec LSI was newly developed for digital HD camcorder, which integrates a video codec, an audio codec, graphics, video interfaces, peripherals, a host processor, and an SDRAM interface. In order to realize low-power real-time receding and playing back system, the LSI uses a software-based codec architecture and a flexible SDRAM control architecture.
