Network-on-chip (NoC) has been proposed as an attractive alternative to traditional dedicated wires to achieve high performance and modularity. Power efficiency is one of the most important concerns in NoC architecture design. The choice of network topology is important in designing a low-power and high-performance NoC. In this paper, we propose the use of the WK-recursive networks to be used as the underlying topology in NoC. We have implemented VHDL hardware model of mesh and WK-recursive topologies and measured the latency results using simulation with these implementation. We also propose a novel approach in high level power modeling based on latency for these topologies and show that the power consumption of WK-recursive topology is less than that of the equivalent mesh on a chip.
