ABSTRACT:
An electronic digital dual processor system including an interface to an external memory in addition to an internal memory. The dual processor architecture includes dual independent and simultaneously operable registers for the temporary storage of data from an arithmetic and logic unit and for memory addressing. The internal memory includes a ROM for storing instructions and a RAM for storing data. The internal memory is also used to store instructions. Control and timing circuitry is included for the generation of microinstructions for the instructions stored in the memory. The control and timing circuitry provide for the simultaneous and independent execution of the microinstructions involving the dual register sets.
