ABSTRACT:
A dual set of memory control circuit cards, one of which services a master processor and one of which serves a slave processor in a data communication Network Support Processor. Each memory control circuit card provides a local memory for each of said processors and further provides access logic circuitry for developing addresses to access an external shared memory means. Control flags and interrupt signals regulate any conflict in operation between the two memory control circuit card units when accessing the commonly shared memory.
