Abstract: An apparatus for carrying out asynchronous communication among integrated circuits for inter-chip communications includes a plurality of senders disposed on an integrated circuit. Each is associated with send-initiate circuitry to indicate a request to send the occurrence of an event. The occurrence of an event causes the sender to transition from a no-event-occurred state to an event-occurred state. An address-generating circuit for generating a unique address is associated with each sender. The send-initiate circuitry of each sender is connected to an arbiter circuit. The arbiter circuit resolves simultaneous requests to send by more than one sender and provides a send-enable signal to the winning contending sender. The send-enable signal resets the selected sender to its no-event-occurred state. The send-enable signal causes the address-generating circuit associated with the winning contending sender to generate the address of that sender and place it on an output bus along with an output-enable signal.
