Abstract

PURPOSE:To increase size of space usable freely by the user, and to freely cope with the increase in a system common area, storing a system common area with one imaginary space. CONSTITUTION:At the access corresponding to a common area, a control register 5-0 is used with the content of a switching register 8, and a control register 5-1 is used with the content of the switching register 8 at the access corresponding to the user's area. When the control register 5-0 is used, a #0 segment table is instructed and offset amount in a segment table 6-0 is given with a part of bits of an execution address 4. When the control register 5-1 is used, #1 segment table is instructed and the offset amount in the segment table 6-1 is given with a part of bits of the execution address 4.
