ABSTRACT:
A microprogram loaded in a microprogram memory by a host CPU is read out by a microprogram read control circuit in a vacant period existing in each cycle of operation of a hardware unit, whereby the microprogram is transmitted to each circuit of the hardware unit through a microprogram read-only bus. Each circuit of the hardware unit comprises a decoder and operation thereof is controlled based on a microinstruction decoded by the decoder.
