Abstract

PURPOSE:To perform the write operation and the execution processing in parallel, by returning a slave sink signal immediately after a memory device receives a master sink signal in the pipeline computer having the operand prefetching function. CONSTITUTION:When a memory device 1 receives a memory bus master sink signal from a CPU 3, and device 1 returns a memory bus slave sink signal immediately simultaneously with starting the write operation. When receiving this memory bus slave sink signal, the CPU 3 restarts the instruction processing. In the CPU 3, a program counter is counted up to transfer the control to the processing for the next instruction after the processing for a store instruction is completed. Thus, the CPU 3 executes successively processings for instructions following the store instruction in the course of the write operation to the memory device 1.
