Abstract
A data processing system includes a plurality of processing units coupled by a plurality of communication links for point-to-point communication such that at least some of the communication between multiple different ones of the processing units is transmitted via intermediate processing units among the plurality of processing units. The communication includes operations having a request and a combined response representing a system response to the request. At least each intermediate processing unit includes one or more masters that initiate first operations, a snooper that receives at least second operations initiated by at least one other of the plurality of processing units, a physical queue that stores master tags of first operations initiated by the one or more masters within that processing unit, and a ticketing mechanism that assigns to second operations observed at the intermediate processing unit a ticket number indicating an order of observation with respect to other second operations observed by the intermediate processing unit. The ticketing mechanism provides the ticket number assigned to an operation to the snooper for processing with a combined response of the operation.
