Star-Type Architecture with Low Transmission
Latency for a 2D Mesh NOC
Abstract— Star-Type Architecture with Low Transmission Latency for a 2D Mesh NOC. The 2D mesh network on chip NOC < Final Year Proejcts 2016 > is a popular NOC topology because of network scalability and the use of a simple routing algorithm. However, the long distance traffic may suffer from high transmission latency. In this paper, we propose an improved design called the star-type architecture in which the long distance traffic is allowed to traverse an additional second level mesh. Simulation results demonstrate that the proposed design can reduce the number of hops traversed for long distance traffic. A 12 × 12 star-type NOC shows performance improvements of 17.2% and 10.3% in comparison with the normal 2D mesh and level-2 mesh architectures, respectively.
