Abstract
A system (and a method) are disclosed for a video processing system with enhanced entropy coding performance. The system includes an entropy decoder configured to divide decoding of an input video stream into arithmetic decoding and syntax decoding. The entropy decoder includes an arithmetic decoding module, a syntax decoding module, a memory management module and a memory buffer connecting the two decoding modules. The arithmetic decoding module is configured to decode the input video stream into multiple bins of decoded input video stream and the syntax decoding module is configured to decode the bins of arithmetically decoded input videos stream into one or more syntax elements. The memory management module uses the memory buffer to accelerate the coding performances of arithmetic decoding and syntax decoding. The system also includes a corresponding entropy encoder configured to encode a video stream with improved coding performance.
