Abstract: Methods and apparatus for entropy decoding are disclosed. Compressed input data representing one or more signals is loaded into one or more registers. A first candidate value for a most probable signal case is prepared from the input data. A second candidate value for a least probable signal case is prepared from the input data. A final signal value for the one or more signals is selected from the first and second candidate values and an output bin value is generated based on the final signal value. A processor readable medium having embodied therein processor readable instructions for implementing the method for entropy decoding is also disclosed. In addition, a method of avoiding a branch instruction in an electronic processing algorithm is disclosed.
