ABSTRACT OF THE DISCLOSURE A microprogrammed control unit with multiple branch capa- bility comprises in addition to a control memory, a first auxiliary read/write memory having low parallelism and a second auxiliary read/write memory having high parallelism. The reading of a micro- instruction from the control memory also causes the reading of in- formation from the first auxiliary memory, such information being used to address the reading of the second auxiliary memory. The information read out from the second auxiliary memory specifies jump conditions to be examined and jump addresses, and extends the informa- tion contained in the microinstruction read out from control memory. Thus it is possible to associate jump microinstruction to operative microinstructions and paricularly multiple branch microinstructions to curtail the design time of the microprograms and the control melory size devoted to store them. A priority network coupled to the second auxiliary memory determines the priority to be followed during the concurrent examination of several jump conditions and selects the jump address among several possible addresses according to the veri- fied jump condition having the highest priority.
