Abstract

The paper presents a novel mapping and routing technique for the mesh based NoC design problem with an objective of minimizing the energy consumption and normalized worst link-load. The proposed algorithm is a particle swarm optimization (PSO) based two phases process, one is mapping core onto NoC, and another is the allocation of routing path. The proposed algorithm uses a novel representation for PSO particle. Experimental results show that the proposed technique can reduce the normalized worst link-load by 20% on average while guarantee a low energy consumption.
