An analytical model for Network-on-Chip with finite input buffer

Abstract

An analytical model is proposed for input buffer router architecture Network-on-Chip (NoC) with finite size buffers. The model is developed based on M/G/1/K queuing theory and takes into consideration the restriction of buffer sizes in NoC. It analyzes the packet’s sojourn time in each buffer and calculates the packets average latency in NoC The validity of the model is verified through simulation. By comparing our analytical outcomes to the simulation results, we show that the proposed model successfully captures the performance characteristics of NoC, which provides an efficient performance analysis tool for NoC design.
