Abstract

PURPOSE: To execute data processes efficiently when an operand overlap is made by performing data transfer processes in a main memory on a n-byte unit.
CONSTITUTION: When the number of bytes to be transferred is stored in length register RL101 and bit information indicating the existence of an operand overlap byte number in operand overlap register ROV102, the number of operand overlap bytes is set. Further a transfer destination address is stored in 1st operand address register part RFA of address buffer 105 and a transfer origin address is in 2nd operand address register part RSA. Then, the existence of an operand overlap is judged from bit information of ROV102 and in accordance with the result, ordinary data transfer processing operations or step operations under farmware controls are carried out.
