    摘要： Piggy-back snoops are used for non-coherent memory transactions in distributed processing systems. Coherent and non-coherent memory transactions are received from a plurality of processing cores within a distributed processing system. Non-coherent snoop information for the non-coherent memory transactions is combined with coherent snoop information for the coherent memory transactions to form expanded snoop messages. The expanded snoop messages are then output to a snoop bus interconnect during snoop cycles for the distributed processing system. As such, when the processing cores monitor the snoop bus interconnect, the processing cores receive the non-coherent snoop information along with coherent snoop information within the same snoop cycle. While this piggy-backing of non-coherent snoop information with coherent snoop information uses an expanded snoop bus interconnect, usage of the coherent snoop bandwidth is significantly reduced thereby improving overall performance of the distributed processing system.

    摘要： Ordered write transactions from requester devices to multiple target devices are controlled using switch point networks. The requester device and the multiple target devices for the write transactions are coupled to a network of interconnected switch points. Write requests are generated for a plurality of parcels associated with a block of data to be written. The write requests have a particular order associated with an order in which the parcels are to be written, and these write requests are provided to the switch point interconnection network in the particular order. At least one of the switch points is then used to control the flow of write requests to the multiple target devices such that the particular order is maintained. In one embodiment, the target devices are memory devices, and the particular order is based upon the AXI (Advanced eXtensible Interface) protocol.
