Abstract

The present invention performs video and audio compression / decompression, video input and output scaling, video input and output processing for enhancement, and system layer functions on a single semiconductor chip. The media processor is compromised of video processor with a SIMD vector engine, audio processor, stream processor, system processor, and video scalers, LUTs and hardware blender. Unified memory architecture is used where these four processors use a shared memory for data and instructions. Data transfers between multiple processors use multiple packet-based unidirectional communication channels via hardware-assisted circular queues in unified memory. The video processor is a SIMD processor coupled to a regular RISC processor as a dual-issue processor. Such integrated and programmable functionality provides implementation of multiple video and audio for compression standards and programmable video enhancement. Important applications of this include Digital TV, IP Video Phone, and Digital Camcorder / Camera.
