Abstract: Systems and methods for improving decoding of encoded image data using parallel multi-bin decoding are provided. In one embodiment, multiple context bins per cycle are decoded for a set of syntax elements, by decoupling and/or retiming particular syntax parsing and/or arithmetic decoding tasks of the decoding process.

Abstract: To improve video parser performance and reduce bottleneck, a video parser may parse a video stream to decode multiple symbols per clock cycle. By decoding multiple symbols per clock cycle, the video parser may decode symbols more quickly and efficiently compared to decoding one symbol per clock cycle, and thus may be less likely to act as a bottleneck for remaining video decoding operations.
