Abstract
A computing system includes a central processor unit (CPU) integrated on a monolithic chip, in combination with a plurality of external memory units. The CPU includes a parallel arithmetic logic unit (ALU) and an internal random access memory interconnected on a common parallel bus with an instruction register. The random access memory defines the general purpose data registers, program and memory address registers, and a multilevel program address stack. Timing circuitry in the CPU enables utilization of either serial or random access external memory units. The timing control of the CPU enables a method of operation characterized by sequential transmission of low order address bits, WRITE data, high order address bits and READ data over a common external parallel bus that interconnects the CPU with the external memory.
