Abstract: PROBLEM TO BE SOLVED: To provide a mounting method of a support to a new real space control bit using an existing translation lookaside buffer mechanism in a microprocessor system. SOLUTION: In a processor system provided with the existing translation lookaside buffer mechanism, in order to support the real space control(RSC) bit which is a new processor control bit, a dedicated space bit which is an existing control bit in the translation lookaside buffer mechanism in re-defined as an ignore common segment bit and a new non-overlapping translation lookaside buffer mechanism entry is generated.
