Abstract
A circuit which controls access of host and remote processors to a single memory. A first flip-flop indicates acceptance or refusal of the processor's memory access requests. A second flip-flop provides a wait signal to the host processor when the remote processor is accessing the memory. A gating circuit causes the first flip-flop to accept the remote processor's access request when both the host and remote processors request memory access at the same time.
