Distributing data to multiple destinations within an asynchronous circuit

摘要

One embodiment of the present invention provides a system that asynchronously distributes data to a plurality of destinations within a digital circuit. Upon receiving a data item to be distributed, the system monitors asynchronous control signals associated with the destinations, wherein a given asynchronous control signal indicates that a given destination is free to receive the data item. For each destination that is free to receive the data item, the system forwards the data item to the destination asynchronously without waiting for a system clock signal, and also changes an asynchronous control signal associated with the destination to indicate that the destination is not free to receive a subsequent data item.
