Abstract

PURPOSE:To shorten the processing time required for operations, by starting the next microstep to perform processings in parallel if the processing time of a microstep does not terminate within the basic time. CONSTITUTION:The output signal FENPR of an FF25 of a decimal operation module BPH12 is supplied to an NAND gate circuit 26 as a gate control command. The CBBSY signal to instruct extension of a microprogram is supplied to a circuit 26 also, and the output signal of the circuit 26 is supplied as the CMBSY signal to the K terminal of a J-KFF27 of a register and control module RCU10. When the CMBSY signal is 1 or 0, the FF27 makes the output signal FNDSY0 or 1-state by the rise of the CSCLK signal. This FNDSY signal is supplied to an inverter 28. The output signal of the inverter 28 is used as the CMDSY signal and as the starting signal for respective operating parts. Thus, even if the CBBSY signal becomes active, the next microstep is started.
