ABSTRACT:
In an interrupt control system for a data processing unit for microprogram control including a processor constructed dividedly between an arithmetic unit and a control unit, a signal representing the absence or presence of an interrupt request to be performed is applied to the control unit so that said control unit reads a microprogram for the interrupt processing from a memory in response to said signal, and said arithmetic unit judges an interrupt source on the basis of the microprogram read out from said memory and performs processing in accordance with the interrupt source.
