Abstract
A system for interprocessor communication including a shared register resource accessible by any one of the processors through the using internal communication paths. The shared register resource is distributed among the processors with each processor including a portion of the total system resource. Each processor includes an access circuit for receiving instructions from the CPU and generating control bytes to be distributed to the shared register resource circuits in each of the processors, which use the control byte to control shared resource access. Each shared register resource circuit is capable of controlling the I/O channels associated with its respective processor. A local access circuit for each CPU is capable of obtaining access to and controlling any of the I/O channels in the system via the shared register resource circuits.
