PURPOSE:To swiftly give a processing chance in response to a high speed processing request, by storing a semihigh speed processing part in a stack cell in accordance with a processing request which has been generated, in a microprogram control device. CONSTITUTION:A microprogram control device 10 is mainly constituted of an offering and indexing controlling circuit 32 for receiving a signal from a channel priority deciding circuit 30 which receives a processing request of plural channels 20, 21,...2n, and a signal from a processing requesting circuit 33 in the device, and for controlling a processing request. An end command is coded to the final step of one processing of a microprogram, but a processing synchronizing command is coded in a high speed processing part, therefore, when this synchronizing command has been generated, if there if other high speed processing request, information which is required for executing the processing of a semihigh speed processing part is stored in a stack 31, and other high speed processing request is processed. |
