Abstract:
A processor includes a microcode storage to store a first microcode subroutine and a microcode caller of the first microcode subroutine. The processor further includes a first microcode alias storage comprising a first plurality of microcode alias locations and a second microcode alias storage comprising a second plurality of microcode alias locations. The processor further includes a first logic, coupled to the first microcode alias storage and to the second microcode alias storage, wherein the first logic is configured to select a first one of a) the first microcode alias storage for storage of a parameter location in one of the first plurality of microcode alias locations or b) the second microcode alias storage for storage of the parameter location in one of the second plurality of microcode alias locations.
