Abstract
An improved programmable compute system and method for executing an H.264 binary decode symbol using only a single instruction and two compute units is achieved by providing not just one rLPS value but all four next possible rLPS values of the current context next state so that there is no delay initially while calculating the correct rLPS because all four are present and any one can be chosen; further all the parameters e.g. value, range, context, and rLPS can be served by only two available 32 bit registers by generating, locally, the MSP ninth bit, of range based on the fact that the range is normalized to a known value in the MSB.
