The recital of Network-on-Chip (NoC) depends on the underlying routing techniques. There are a lot of requirements that has to be met. Such performance metrics are minimum latency, least power and maximum throughput. This paper deals with XY route, PROM routing, FTXY routing and DyAD routing on 5x5 2D torus topology. The simulation is performed on nirgam NoC simulator version 2.1 for constant bit rate traffic condition. The simulation results reveals the dominance of XY, PROM, FTXY and DyAD algorithms depicting the minimum values of overall average latency per channel (in clock cycles per flit) as 0.409836 overall average latency per channel (in clock cycles per packet) as 6.2535, average throughput as 16.68, and total network power as 35.6768 mw, achieved for FTXY routing algorithm.
