Thermally Aware LVCMOS based Low Power Universal Asynchronous Receiver Transmitter Design on FPGA

Abstract

Green communication is the latest research trend practiced by researcher in green computing and network communication. There is no extensive work in green UART design. In order to fill this research gap, we are going to design LVCMOS based energy efficient Universal Asynchronous Receiver Transmitter (UART) that will create an avenue for IO standards based green communication. UART (Universal Asynchronous Receiver Transmitter) is a kind of serial communication protocol; mostly used for short-distance low speed, low-cost data exchange between computer and peripherals. Various energy efficient techniques have been applied to the design along with the change in IO standards. It has been concluded that there occurs 97.65% reduction in clock power, 75.14% reduction in I/O power, 7.19% reduction in leakage power, 17.37% reduction in junction temperature, and 71.12% reduction in total power dissipation in case SSTL2_II IO/standard, thus it is considered to be most energy and power efficient IO standard to be used in the future.
