Abstract

PURPOSE:To increase operation speed by executing the access of ROM considering the access time of a ROM earlier than the final digit processing of the data processing of a RAM in one instruction. CONSTITUTION:When the access time of a ROM 1 is two digits, it is detected before two digits of a final processing digit, the ROM 1 is made access and a next instruction is read. While the ROM 1 is made access, the processing of two remaining digits at a preceding instruction is executed. In the ROM 1, the program to control the processing up to before two digits of the final digit processing is written beforehand.
