    摘要: A control device which controls a plurality of controlled devices by time shared control in a microprogram control system and has one control memory, a plurality of microinstruction registers, the outputs of which are applied to the controlled devices, circuits for memorizing microinstruction execution requests corresponding to microinstruction type and the controlled devices, and a selecting circuit for selecting a microinstruction register for storing a microinstruction read out from said control memory in each machine cycle and the controlled devices to be controlled. The field of the microinstruction indicates the execution and type of the next microinstruction after the next machine cycle to a given controlled device. When the execution of the next microinstruction is indicated, this request and the microinstruction type are memorized by microinstruction request holding circuits corresponding to the controlled circuits respectively and any selected controlled circuit, and the microinstruction is read out of the control memory. Consequently, the instruction stored in one microinstruction register may control one controlled circuit while other instructions stored in the other microinstruction registers may control the other controlled circuits in time-shared parallel relationship.
