Abstract: A FLEXIBLE PROCESSOR ON A SINGLE SEMICONDUCTOR SUBSTRATE A processor is provided that is fabricated on a single semiconductor substrate. The processor includes an AND array for receiving program instructions from input sources external of the processor and for generating product signals. An OR array is provided and interconnected to the AND array for receiving the product signals and for generating a plurality of control signals. A register array receives ones of the plurality of control signals and transfers data between the processor and data sources external of the processor. An arithmetic and logic unit array is also provided on the semiconductor substrate and interconnected to the register array and the OR array for executing operations on data received from the register array in accordance with ones of the plurality of control signals to generate output data. A control register is further provided and is interconnected to the OR array and the AND array for receiving ones of the plurality of control signals for controlling execution of the program instructions within the AND array.

Abstract: MICROWORD CONTROL SYSTEM UTILIZING MULTIPLEXED PROGRAMMABLE LOGIC ARRAYS 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 mutliplexing circuitry for supplying microwords from different ones of the programmable logic array mechanisms to the control circuitry during different time intervals.

Abstract: A multi-bit operation code (22) is decoded into a single product term in the AND array (20) of a programmable logic array. That single product term is then processed through a clock (45) driven sequencer (32) to generate a plurality of sequential product term signals. These sequential product terms are decoded by the OR array (30) of the programmable logic array to generate a plurality of sequential time states (58) corresponding to the decoded operation code (22).
