ABSTRACT:
A control circuit controls a hardware portion based on a microprogram set by a host CPU. Microinstructions constituting the microprogram comprise an instruction for setting an initial value of an address counter for reading microprogram as well as an instruction for controlling the hardware portion. The initial value setting instruction comprises an initial value setting instruction which uses the state of a flag register, which is set dependent on a change of state generated from the arithmetic processing in the hardware portion, as a condition. Therefore, the flow of reading of the microprogram can be changed corresponding to the change of the state generated by the arithmetic processing in the hardware portion.
