Abstract

Systems devices and methods are described including using during a single clock cycle one Context Based Adaptive Arithmetic Coding (CABAC) engine to encode one bin value and another CABAC engine to encode another bin value. The probability state index of each CABAC engine may provided to the other CABAC engine when the bin values are encoded.
