Abstract

PURPOSE: To increase the degree of freedom on control program constitution by selecting and executing sequentially on time division basis one of plural program statuses for instruction memory access and using an execution instruction to access also the content of the other program statuses.
CONSTITUTION: In a program status PSA execution time, the read/write (R/W) of the PSA is attained by a PS switch control circuit 12 and a PSA R/W control circuit 14 and in addition to the function, the R/W of a PSB is attained by the PS switching control circuit 12 and a PSB R/W control circuit. This operation is realized by using an execution instruction to control PSA, PSB R/W signals generated from the PSB R/W control circuit 14 and the PSB R/W control circuit 15 provided independently of the control signals from the PS switching control circuit 12A to a PS operation selection circuit 11A.
