PURPOSE:To shorten the time of data processing which is performed accompanying the reading or writing of data differing in data length. CONSTITUTION:When a general microcomputer 101 reads an access (read/write) instruction out of a program memory part 140, a decoder 102 detects the access instruction on a data bus 110 and a signal generating circuit 23 accesses a memory part 14. Further, a read data processing circuit 22 or write data processing circuit 24 processes the data according to the access contents. |
