PURPOSE: To improve the throughput of a store instruction by performing the execution of the store instruction to increase/decrease an address at a fixed interval with a request pipe of a small metal quantity.
CONSTITUTION: At a vector processor 2, plural request pipes 20A0-20B1 to issue a memory request are provided at a main storage device 1. The request pipes 20A0-20A1 process the store instruction which increases/decreases the address at the fixed interval and smaller than the 1/2 block size of a buffer memory 30 in a scolar processor 3, and the request pipes 20B0-20B1 process all the store instructions. An instruction control part 21 selectively uses the request pipes 20A0-20B1 corresponding to the store instruction to increase/ decrease the address at the fixed interval and the other store instruction.
