PROBLEM TO BE SOLVED: To provide a BISC type processor capable of further shortening executing time and performing relative diverging function. SOLUTION: In the BISC type processor, in which a command set is inter- register data transmission by means of internal busses 102 to 104, having function units 151, 156 and 161 and a register file 101 including function registers 111 to 114, 121 to 123, 131, 132, and 141 and transmitting data among registers, the processor is comprised of a first means 165 having a flag showing the propriety data transmission of function registers 111 to 114, 121 to 123, 131, 132, and 141 and a second means 166 informing the function units 151, 156, and 161 of the pros and cons of data transmission by referring to the flag. The processor is also comprised of an address calculating function unit 151 calculating a memory address, and a memory controlling function register 121, a memory inputting function register 122, and a memory outputting function register 123 connecting to the address calculating function unit 151. |
