An Efficient Way to Increase Performance by Using Low Power Reconfigurable Routers

In this paper, the advantage of the use of a NoC with reconfigurable routers has been presented instead of homogeneous ones. In this paper, the authors propose the use of a reconfigurable router, where the buffer slots are dynamically allocated to increase router efficiency in a NoC, even under rather different communication loads. In the proposed architecture, the depth of each buffer word used in the input channels of the routers can be reconfigured at run time. Using reconfiguration, one can dynamically change the buffer depth to each channel, in accordance to the necessity of the application, increasing the power efficiency of the system for the same performance level.
