PURPOSE:To automatically synthesize control logics of the microprogram system by storing structures of various control circuits used in the microprogram system as models. CONSTITUTION:A logic circuit designer inputs address order information of a microprogram to be designed and information related to branch functions from an input/output device. Address order information is stored in a mu address order storage part 1, and information related to branch functions is stored in a branch function information part 2. Bits of information related to various control structure models are stored in a control information storage part 3. A control model meeting the purpose is selected from contents of the storage part 3, and unnecessary circuit parts existing in this selected control model are extracted and eliminated to obtain a control structure where redundancy is excluded. This control structure is subjected to the circuit detailing processing, thus automatically synthesizing a control structure of the microprogram system.
