PURPOSE:To reduce the time loss due to the conflict of memory access, by making use of an idle time of memory access which is produced by the combination of instruction to be processed. CONSTITUTION:A request accepting circuit 6 accepts preferably the reading request made from an address calculating circuit 2, selects the reading request and the address data of a reading operand to give it to a cash memory circuit 8, and reads the contents of a designated memory address to transfer it to an operand register of an arithmetic circuit 4. In case a writing request is made from an address buffer circuit 10, the circuit 6 selects the address data extracted from the circuit 10 plus the writing request to supply them to the circuit 8. The circuit 8 stores the data of a data buffer circuit 11 to a memory address that is designated by an address data supplied via the circuit 6. |
