摘要: A CABAC decoding engine is devised to cover all aspects of CABAC-coded syntax elements for AVC. This acts like a Co-processor another Processor (CPU), which guides the bit stream. The or has following highlights: unique context model retrieving and storing method developed allow complete element be decoded in one hardware (H/W) execution cycle (not necessarily clock cycle.); H/W assisted approach provided accelerate initialization; based incorporated fast de-binarization; block instead by one; dedicated accelerators are decode special elements.
