Abstract

An interface for use between an asynchronous domain and a synchronous domain is described. The asynchronous domain is characterized by transmission of data in accordance with a delay-insensitive handshake protocol. The synchronous domain is characterized by transmission of data in accordance with transitions of a clock signal. The interface includes a datapath operable to transfer a data token between the domains. The interface also includes control circuitry operable to enable transfer of the data token via the datapath in response to a transition of the clock signal and at least one completion of the handshake protocol.
