Abstract
A device employing techniques to optimize Context-based Adaptive Binary Arithmetic Coding (CABAC) for the H.264 video decoding is provided. The device includes a processing circuit operative to implement a set of instructions to decode multiple bins simultaneously and renormalize an offset register and a range register after the multiple bins are decoded. The range register and offset registers may be 32 or 64 bits. The use of a larger range register allows renormalization to be skipped when enough bits are still in the range register.
