Summary
Multiple processors enhance performance and ease expansion. Processors may be tightly interconnected and execute small tasks on demand, e.g., data flow programming. Another approach is a network of communicating processors with pre-assigned tasks. For instance one processor may handle disk i/o while another manages the display screen. Multiple processors are also used for redundant reliability. The shadow processor has a watchdog timer and a means of taking control if the main processor stops regular execution. (cbb 5/80)
