Abstract
A microword control system is provided for producing the sequences of microwords used to control the execution of processor instructions in a microprogrammed digital data processor. This microword control system includes a plurality of programmable logic array mechanisms responsive to the processor instruction to be executed for individually producing different ones of the microwords needed to execute such instruction. This microword control system also includes microword-responsive control circuitry for controlling the operation of the data processor. This microword control system further includes multiplexing circuitry for supplying microwords from different ones of the programmable logic array mechanisms to the control circuitry during different time intervals.
