Predictable Dynamic Virtual Channel Allocation Strategy for Network on Chips

Abstract

This paper presents a dynamic power management technique, namely dynamic virtual channels allocation (DVCA)， for improving the performance of virtual channels utilization in network on chips. The proposed method uses of the traffic conditions and past buffer utilization to dynamically predict the number of virtual channels. The number of VCs will be allocated to the corresponding input channel depending on the traffic load. This method reduces the number of buffer and the power consumption of router under average the data communication rate. The experimental results show that the proposed method improves the data communication rate by 77.24% and number of virtual channel prediction by 50%.
