Abstract

Considering that routing algorithms for the Network on Chip (NoC) architecture is one of the key issues that determine its ultimate performance, several things have to be considered for developing new routing algorithms. This includes examining the strengths, capabilities, and weaknesses of the commonly proposed algorithms as a starting point for developing new ones.
Because most of the algorithms presented are based on the well-known algorithms that are studied and evaluated in this research. Finally, according to the results produced under different conditions, better decisions can be made when using the aforementioned algorithms as well as when presenting new routing algorithms. In this research, we first describe the existing algorithms include: XY, YX, Odd- Even and DyAD. We then evaluate each of the routing algorithms which naturally have their own strengths and weaknesses under different conditions. In the first scenario, based on the criteria of average latency, average throughput and average energy consumption in determining the final performance of the network on the chip, we show the algorithms in terms of their performance by deterministic and adaptive routing algorithms. In the second scenario, we evaluate the algorithms based on the network size and the number of cores on the chip. As a result, these algorithms can make better decisions when using these algorithms as well as when presenting new routing algorithms, considering the results produced under different condition.
