Abstract
PURPOSE: To enable rewriting of the order by handling the order register in the same level as other general-purpose registers and thus to ensure the process for the versatile data with the minimum quantity of both the hardware and the program.
CONSTITUTION: The following units are provided: program memory 1 to store the program comprising plural number of orders; address register 7 to store the address which designated the order storage unit within memory 1; plus order registers 3 and 4 to store the orders read out from memory 1. In addition, external register 6 is provided to store the order given from outside, along with decoding control circuit 2 which delivers control signal 17 after decoding the order given from order register 3 plus selection circuit 8 which selects the output with the output of registers 3W7 and signal 17 of circuit 2 used as the input and then supplies the output to arithmetic circuit 9. Thus, the contents of register 6 is stored in registers 3, 4 and 5 based on signal 17 decoded through circuit 2.
