Abstract: Disclosed are ticketed flow control mechanisms in a processing system with one or more masters and one or more slaves. In an aspect, a targeted slave receives a request from a requesting master. If the targeted slave is unavailable to service the request, a ticket for the request is provided to the requesting master. As resources in the targeted slave become available, messages are broadcasted for the requesting master to update the ticket value. When the ticket value has been updated to a final value, the requesting master may re-transmit the request.
