A processor comprising a decode logic coupled to a first storage unit and comprising a data structure. The processor also comprises a second storage unit coupled to the decode logic. The decode logic obtains a single instruction from the first storage unit and, if indicated by a first bit in the data structure, processes a group of instructions in lieu of the single instruction, where the single instruction requires an operand. If indicated by a second bit in the data structure, the decode logic obtains the operand from the first storage unit, modifies the operand, and stores the operand to the second storage unit for use by the group of instructions. |
