Abstract:
1. A system comprising: an interconnect; a plurality of agents coupled to the interconnect; and a switch coupled to the plurality of agents and the interconnect, wherein each agent of the plurality of agents that is configured to source transactions on the interconnect is configured to transmit requests to the switch via a communication path separate from the interconnect, and wherein each request comprises an address of the transaction and a command, and wherein the switch is configured to arbitrate among the requests from the plurality of agents and to issue a selected request on the interconnect, wherein the selected request is a winner of the arbitration; wherein a first agent of the plurality of agents is one of the agents that is configured to source transactions on the interconnect, and wherein the first agent is configured to transmit a first request to the switch, and wherein the first agent is configured to detect that the first request has been granted by the switch responsive to the first agent detecting the first request transmitted as an address phase of the first transaction on the interconnect, and wherein a second path from the interconnect to the first agent excludes the switch.
