Method for identifying the orignal source device in a transaction request initiated from address translator to memory control module and directly performing the transaction therebetween

摘要

A method for issuing device requests by proxy in a system using distributed control through a multi-port switch. A device issues a request to a central switch indicating the original requester as the source rather than itself. This passes responsibility for the control of the actual data transfer back to the original requester, and the device is no longer involved.
