Evaluation of low power consumption network on chip routing architecture

Abstract

Network on Chip (NoC) is growing technology whereby multiprocessor state interconnect patterns are formed. NoC technology is adapted to support a variety of multiprocessor requirements. The existing designs do not support the growth requirements of user applications. Because of the complex routing connections, several problems exist about traffic congestion and Power consumption contributing to a network's low efficiency. Traffic Congestion, Power consumption, and latency are a significant concern in Network on Chip architectures because of various dynamic routing connections. The existing models do not consider all the above-mentioned factors and struggle to achieve higher performance. The previous methods do not trigger the circuits according to the traffic condition and maximum power consumption. For this, the proposed High-Speed Virtual Logic Network on Chip router architecture is utilized for controlling the traffic congestion and deadlock issues, reduce the latency by selecting the minimal interval paths. In this research work, an architecture containing a Virtual router is introduced which yields low power consumption resulting in improving the performance of a network by performing the routing in a diagonal direction along with the other directions. Also, the method selects an optimal path according to various conditions that neglect the unnecessary triggering of chips which reduces the power consumption. The proposed model considers the dynamic congestion and route available to perform routing with the least power consumption. By comparing both the architectures, VC Router outperformed 15% of low power consumption for the 8-bit system, 10% of low power consumption for the 16-bit system, and 22% of low power consumption for the 32-bit system.
