Effect of Different Nano Meter Technology Based FPGA on Energy Efficient UART Design

In this paper, the main aim of authors is to design UART that is implemented on Xilinx ISE Design 14.1 and results were tested on Virtex-4 90nm FPGA, Virtex-5 65nm FPGA and Virtex-6 40nm FPGA. For 90nm FPGA, device used is Virtex-4, part name is xc4vfx12, package used is sf363, and it is working on -12 speed grade at an ambient temperature of 50.0 °C. For 65nm FPGA, device used is Virtex-5, part name-xc5vlx20t, package used is ff323, and it is working on -2 speed grade at an ambient temperature of 50.0 °C. For 40nm FPGA, device used is Virtex-6, part name is xc6vlx75t, package used is ff484, and it is working on -3 speed grade at an ambient temperature of 50.0 °C. In this paper, UART code is written in Verilog language and power is analyzed for 65nm, 90nm and 40nm technology based FPGA.
