Abstract
The present application describes a method and a system for executing instructions while reducing the logic required for execution in a processor. Instructions (e.g., atomic, integer-multiply, integer-divide, move on integer registers, graphics, floating point calculations or the like) are expanded into helper instructions before execution (e.g., in the integer, floating point, graphics and memory units or the like). Such instructions are treated as complex instructions. The functionality of a complex instruction is shared among multiple helpers so that by executing the helpers representing the complex instruction, the functionality of complex instruction is achieved. The expansion of complex instructions into helper instructions reduces the amount of hardware and complexity involved in supporting these individual complex instructions in various units in the processor.
