摘要
A method and system for dividing computer processor registers into sectors and storing frequently used data in the most significant unused sectors. The method includes sector renaming that is performed on each individual sector (i.e., on a sector-by-sector basis) rather than renaming an entire processor register. A register is divided into sectors such that the smallest accessible unit for an instruction in each register can be uniquely addressed and renamed. A register file is divided into sectors so that each process register can be uniquely addressed and renamed. The most significant sectors of the processor registers are used to hold pre-assigned values therein. Data previously loaded into processor register sectors is stored in the most significant sectors of the processor registers for possible future referencing and use. The method also includes establishing a sign-extend memory that includes at least one sign-extend bit in a sector status table.
