ABSTRACT:
A method and system are provided for generating a synchronized handshake between communicating parts of a digital system operating from a common clock. A request signal is sent from an initiating station to a responding station. The responding station acknowledges receipt of the request by sending an acknowledge signal back to the initiating station, thereby completing a so-called handshake. In accordance with the invention both the request and acknowledge signal are pulses of a fixed duration greater than one but less than two clock cycles. A new request signal may be transmitted concurrently with the reception of an acknowledge signal, resulting in a maximum handshake rate of one half of the common clock rate.
