In this paper, a low power flexible Network Interface (NI) Architecture for Network on chip (NoC) is proposed. The flexible run time configuration controller in the proposed NI plays a vital role to reduce the power by enabling and disabling the entire asynchronous First In First Outs (FIFOs) based on the traffic conditions between the router and the processing elements (PE). The NI has been implemented in Xilinx Virtex-5 XC5VLX110T FPGA. Experimental results show that the proposed low power NI offers a power improvement of 37%, when both FIFOs are inactive and 32%, when only one FIFO is active.
