Evaluation of Effect of Packet Injection Rate and Routing Algorithm on Network-on-Chip Performance

Mostafa Haghi, M. Asha Rani

In system on chip (SOC) with NOC interconnection paradigm, PIR (Packet Injection Rate) and Routing algorithm are two critical factors that affect the efficiency of SOC communication. Its observed that NOC may saturate at certain rate of injection packets. The effect of PIR on three routing algorithms in switch-based NOC with limited number of IP blocks is studied in this paper. The chosen algorithms for this work are FULLY ADAPTIVE, XY and WEST FIRST, Mesh topology is applied with 16 cores (N*N style). Performance evaluation is conducted based on flitaccurate and open source SystemC simulator. Eventually the critical points in saturation area are determined for above algorithms and throughput, power consumption and delay are compared for mentioned routing algorithms.
