Abstract

PURPOSE:To process execution instruction efficiently, by generating an interruption with an execution instruction discriminating flag and assigning the specific address of a main memory as a storage address of a subordinate instruction. CONSTITUTION:When a request for instruction readout is given to a main memory 1, the execution insturction of a content 41 is read out, and when the instruction is interpreted as the execution instruction, an execution instruction discriminating flag 58 is set to save the address of the instruction itself to an operation processing section 57. A subordinate instruction 43 is read from the main memory 1, changed and stored in a specific address of the main memory 1. A value in the specific address is set to a memory address register 51, and when the readout from the main memory 1 and the excution of the readout instruction are finished, since the flag 58 is set, the interruption takes place and the interruption processing is made. Further, the flag 58 is reset and the procedure returns to the normal instruction processing procedure.
