Claim One:
1. In an integrated circuit, for use in a neuromorphic system, apparatus for communication of information identifying each occurrence of multiple random events from a plurality of initiators across a single bus to a receiver which generates a separate acknowledge signal in response to receipt of said information of each of said events, comprising: a plurality of event generators disposed on the integrated circuit, each of said event generators having only two states which include a first no-event-occurred state and a second event-occurred state; a send-initiate circuit, associated with each of said event generators, for changing a request-to-send signal from a reset state to a set state indicating a request to send information identifying the occurrence of an event in response to said event-occurred state of its associated event generator; an asynchronous arbiter circuit, coupled to said send-initiate circuit and asynchronously responsive to multiple simultaneously extant request-to-send signals in set states, for sending a single select signal to one event generator in its event-occurred state; event generator reset means, in each of said event generators, for causing a transition from said second event-occurred state to said first no-event-occurred state in response to said select signal; address generating means, associated with each of said event generators, for generating a unique address onto the single bus, said unique address identifying its event generator, in response to said select signal; and send-initiate-circuit reset means for placing all said request-to-send signals into reset states in response to each separate acknowledge signal.
