Abstract
A technique for increasing the number of physical segment registers by renaming logical segment registers into a larger register space. The remapping of the segment registers allows for instructions accessing the segment registers to be executed non-serially. The renaming of segment registers is achieved by assigning a shadow register to a segment register name. Thus, a pair of registers are physically available for a specified logical register in an instruction set to be renamed. Two bits, designated as the PSEG and SPEC bits, are used to control the remapping.
