摘要
The present application describes a method and a system for facilitating atomicity of complex instructions in processor execution of helper instruction. Atomic complex instructions are handled by stalling the fetching of instruction upon recognizing atomic instruction in a group of fetched instructions. Complex atomic instructions are expanded into helper instructions before execution (e.g., in the integer, floating point, graphics and memory units or the like). Stalling the fetching facilitates the execution and completion of corresponding helper instructions and maintains the atomicity of the complex instruction.
