Abstract
A context-based adaptive binary arithmetic coding (CABAC) decoder includes a bin decode circuit and a context update circuit. The bin decode circuit supports decoding of multiple bins in one cycle. The multiple bins include a first bin and a second bin. The bin decode circuit generates a bin value of the first bin according to a first set of multiple contexts, a first range and a first offset, and generates one bin value of the second bin according to a second set of multiple contexts, a second range and a second offset. The context update circuit updates the first set of multiple contexts in response to the bin value of the first bin, to generate a first set of multiple updated contexts, and updates the second set of multiple contexts in response to said one bin value of the second bin, to generate a second set of multiple updated contexts.
