Abstract
A microprogram-coupled multiple-microprocessor module receives a system command system status and associated data. The system command and the system status can be directly used as an address or mapped into a microprogram memory address to initiate micro-subroutines. The module can serve as a basic processor and its microprogrammability gives it a high degree of flexibility and modularity. A five-microprocessor module is employed in one example. Basic microprogramming techniques used in the module include a multiple-way microprogram branch technique. The organization of the module is systematic and structured and the microprogramming for the module is a comparatively simple procedure. The module achieves an improved rate of instruction execution at a relatively small cost in the number of clock cycles required.
