1. A programmable compute system for executing an h.264 binary decode symbol instruction comprising: a first compute unit including a first range circuit responsive to a current range of Least Probable Symbol (rLPS) current range and a current value for calculating Most Probable Symbol (MPS) and Least Probable Symbol (LPS) range values and setting a first flag to select one of them; a range normalization circuit, responsive to the selected one of said MPS and LPS range values to provide normalized range; and a current rLPS circuit including a first look up table responsive to a state, said flag and said normalized range for generating a current context next rLPS; a second compute unit including a second range circuit responsive to the current rLPS range and value for calculating MPS and LPS range values and setting a second flag to select one of them; a value update circuit, responsive to a current value and a difference between the current range and current rLPS for calculating MPS and LPS value values and responsive to said second flag to select one of them; a value normalization circuit, responsive to said selected range value and a selected value value to provide the next value; and a current context update circuit responsive to current context MPS and state, for determining MPS and LPS state from a second look up table and selecting one of them in response to said second flag and generating an MPS and negated MPS bit and providing a next context MPS and a state and a decode symbol; a third compute unit including a third range circuit, responsive to current rLPS, range and value for calculating MPS and LPS range values and setting a third flag to select one of them; a second range normalization circuit, responsive to the selected one of said MPS and LPS range values to provide normalized range; and a next new context rLPS circuit, responsive to the new context state and the normalized range to determine from a third look up table the next rLPS for the new context.
