ABSTRACT:
In a processor speculatively executing instructions which specify logical addresses, a method and apparatus for speculatively converting logical addresses to physical addresses. The processor has a register window movable within a register file, a window pointer register maintaining a value corresponding to the location of the window in the register file, a speculative window pointer register maintaining a speculative value of the window pointer register. A controller identifies an instruction expected to modify the value in the window pointer register, and in response to identifying the instruction the controller modifies the speculative value. A mapper, coupled to the speculative window pointer register, converts the instruction specified logical addresses to physical addresses based on the speculative value contained in the speculative window pointer register.
