Distributing data to multiple destinations within an asynchronous circuit

An apparatus for asynchronously distributing data to a plurality of destinations within a digital circuit, comprising:

• an input that is configured to receive a data item to be distributed to at least one destination in the plurality of destinations;
• a plurality of asynchronous control signals associated with the plurality of destinations, wherein a given asynchronous control signal indicates that a given destination is free to receive the data item;
• and
• an asynchronous data transfer circuit that is configured to monitor the plurality of asynchronous control signals;
• wherein for each destination that is free to receive the data item, the asynchronous data transfer circuit is configured to,
• forward the data item to the destination asynchronously without waiting for a system clock signal, and to
• change an asynchronous control signal associated with the destination to indicate that the destination is not free to receive a subsequent data item.
