ABSTRACT:
A synchronizing apparatus couples two independently operated bus systems, each bus system capable of generating asynchronous control signals for controlling the states of all of the units within the entire system. The apparatus includes a pair of synchronizer storage elements, each connected to receive, store, and transmit an asynchronous control signal from one of the bus systems to the other bus system. The synchronizer elements are connected to receive a set of complementary clocking signals from a timing source. Both synchronizer elements are interconnected so that by decoding the internal states of such elements only one of the control signals will be transmitted when both synchronizer elements simultaneously receive control signals from both buses thereby ensuring reliable operation throughout the entire system.
