Waved time multiplexing

摘要

Technologies generally described herein relate to waved time multiplexing. In some examples, a command flit can be transmitted from a sender node of a network-on-chip (“NOC”) to a destination node of the NOC via an intermediate node along a circuit-switched path. The command flit can include an interval period and a release duration. When the command flit has been transmitted, one or more data flits can be transmitted from the sender node to the destination node via the intermediate node along the circuit-switched path. The sender node, the destination node, and the intermediate node can be configured to reserve router resources of the sender node, the destination node, and the intermediate node respectively for circuit-switched traffic during a use duration of the interval period and to release the router resources for packet-switched traffic during the release duration in a waved time multiplex arrangement.

1. A method for operating a hybrid circuit-switched and packet-switched network-on-chip (NOC), the method comprising:
transmitting a setup packet for requesting establishment of a circuit-switched path from a sender node on the NOC to a destination node on the NOC, wherein the circuit-switched path includes one or more intermediate nodes arranged between the sender node and the destination node; when the setup packet traverses the intermediate nodes, at each intermediate node, establishing the circuit-switched path; receiving the setup packet at the destination node; in response to receiving the setup packet at the destination node, selecting a primary utilization rate from one or more utilization rates included in the setup packet, determining an interval period for circuit switched traffic and a release duration for packet-switched traffic or other circuit-switched traffic based on the primary utilization rate, and generating an acknowledgement packet for confirming establishment of the circuit-switched path, wherein the acknowledgement packet includes the interval period and the release duration; and transmitting the acknowledgement packet from the destination node to the sender node, wherein the sender node reserves router resources of the sender node for circuit-switched traffic during a use duration of the interval period and releases the router resources for packet-switched traffic or other circuit-switched traffic during the release duration.
