Title: Multiprocessor interface

Journal Article · · IEEE Micro; (United States)

The author describes a hardware link between two microprocessor systems, each of which can be regarded as a peripheral of the other. The link uses two MC 68230 PI/T-parallel interface/timer-chips, one at each processor. Each PI/T interfaces to the high-speed bus signals coming from its processor, and to a shared TTL sequencer. The sequencer controls the transfer of data over a bidirectional data bus between the two PI/Ts, at a data rate optimized to the individual application. This interface is designed to allow the programmer a choice of data transfer control methods: software polling of a status register, either of two different interrupt request protocols, or DMA requests.
