Download Now Free registration required

Executive Summary

This paper proposes a new mesh-typed NoC architecture which aims at enhancing network performance while keeping implementation cost feasible. The result is a Diagonally-linked mesh (DMesh) NoC that uses wormhole packet switching technique. Together with the proposed adaptive quasiminimal routing algorithm, DMesh improves average latency and saturation traffic load. In addition, logic synthesis results show that adding diagonal links is a more area-efficient way for increasing network performance than using large buffers.
