Methods And Systems For Controlling Ordered Write Transactions To Multiple Devices Using Switch Point Networks

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.

1. A method to control ordered writes of data from a requester device to multiple target devices, comprising:
generating a plurality of write requests for a plurality of parcels associated with a block of data to be written from a requester device to multiple target devices, the write requests having a particular order in which the parcels are to be written to the multiple target devices; sending the write requests to a network of a plurality of interconnected switch points in the particular order, the requester device and the multiple target devices being coupled to the plurality of interconnected switch points; and controlling flow of the write requests to the multiple target devices using at least one of the switch points such that the particular order is maintained.
