ABSTRACT:
According to one embodiment, a method features operations for executing instructions in an instruction window. The first and second instructions are examined to determine their sources and destinations. The written on bit of the first instruction is set to a “written on” state if the destinations of the first and second instructions are the same while a used bit of the first instruction is set to a “used” state if the source of the second instruction is the destination of the first instruction. Thereafter, a priority of the first instruction can be determined from the written on and used bits.
