ABSTRACT:
One embodiment of the present invention provides a system that dynamically allocates physical registers in a windowed processor architecture. The system includes a physical register file and a register map that maps architectural registers defined within an executing program to physical registers within the physical register file. The system also includes a window allocation mechanism that allocates a new name space for a register window without allocating physical registers for the register window, thereby allowing the physical registers to be dynamically allocated as needed instead of being allocated at window initialization time.
