Power Optimization using Label Switching Router and Predictor Technique in 2 Dimensional Network on Chip


Objectives: To design a label switched- predictor router in 2D Network on chip and compare the power consumption in label switched router and label switched predictor router. Methods/Statistical Analysis: To implement label switching technique with Maxflow Fulkerson algorithm to find the routing path. The modification added in this paper is the predictor which predicts whether the data is repeated data or new data and if it is a repeated data, the previous output will be considered by which power consumption is improved. An 8 bit data is provided and compared with the previous data to check for repeated data and Xilinx software and ISIM simulator was implemented. Findings: The power consumption in label switched router is 177.14mW and in label switched-predictor router is 155.85mW. There is 12 % improvement in power consumption. When the size of network increases; the power consumption for the repeated data inputs will be reduced by this implementation. Application/Improvements: This work can be extended by applying streaming video inputs to the 3x 3 mesh network and compare its performance.
