Abstract

Excess power dissipation along with increased leakage currents in router buffers and crossbars are becoming a major constraint that is affecting the performance of Network-on-Chips (NoCs) architectures. In this paper, we design channel buffers and router crossbars in a concentrated torus topology (CTorus) which is a dual network without the additional area overhead. When compared to other dual networks, CTorus improves saturation throughput by 11-20% for synthetic traffic and improves speedup by 1.78-2.15X for real benchmark traces such as PARSEC and SPEC CPU2006. When the energy-efficient buffer and crossbar organization was inserted into our CTorus topology, we reduced energy dissipation by 32% and area by 53% on average over mesh2X, CMesh2X and FBfly2X.
