Abstract
Message passing circuitry comprises lookup circuitry responsive to a producer request indicating message data provided on a target message channel by a producer node of a system-on-chip, to obtain, from a channel consumer information structure, selected channel consumer information associated with a given consumer node subscribing to the target message channel. Control circuitry writes the message data to a location associated with an address in a consumer-defined region of address space determined based on the selected channel consumer information. When an event notification condition is satisfied for the target message channel and the given consumer node, and an event notification channel is to be used, event notification data is written to a location associated with an address in a consumer-defined region of address space determined based on event notification channel consumer information associated with the event notification channel.
