A Kind of “4-high-1-low” Traffic Model for On-Chip Crossbar

It is important to design on-chip crossbar by using appropriate traffic model. A kind of ¿4-high-1-low¿ traffic model is presented based on analysis of the character of unbalanced traffic among input port and output port of on-chip crossbar in 2D-Mesh NOC. Then it is analyzed how the performance of on-chip crossbar is impacted by ¿4-high-1-low¿ traffic model according to simulation. The impact of ¿4-high-1-low¿ traffic model is concluded finally and open problems are presented.
