The bandwidth requirement for each link on a network-on-chip (NoC) may differ based on topology and traffic properties of the IP cores. Available bandwidth on an asynchronous NoC link will also vary depending on the wire length between sender and receiver. We explore the benefit to NoC performance when this property is used to increase bandwidth on specific links that carry the most traffic of an SoC design. Two methods are used to accomplish this: specifying router locations on the floorplan, and adding pipeline latches on long links. Energy and latency characteristics of an asynchronous NoC are compared to a similarly-designed synchronous NoC. The results indicate that the asynchronous network has lower energy, and link-specific bandwidth optimization has improved the average packet latency. Adding pipeline latches to congested links yields the most improvement. This link-specific optimization is applicable not only to the router and network we present here, but any asynchronous NoC used in a heterogeneous SoC. |
