Network on Chip for Parallel DSP Architectures

摘要

Network-on-Chip is a new methodology of System-on-Chip design. It can be used to improve communication performance among many computing nodes of parallel DSP architectures. Simulations based on the 16-node 2D-mesh DragonFly DSP architecture show that the routing distance of 72.9% inter-node communication is 1. A fast local router is proposed to improve the performance of this communication. Experiments on our simulator show that overall inter-node communication delay is decreased by 59.4%.
