Capacitance and frequency scaling based energy efficient image inverter design on FPGA

Abstract

In this work, Capacitance scaling and Frequency scaling is done in order to make energy efficient Image Inverter design. Frequency scaling results variations in power consumption and the Junction temperature of Image Inverter. There is 93.33% change in Logic power, 98.06% change in Signals power, 99.00%change in IOs power, 92.02% change in Leakage power and 77.6% change in Junction temperature. Clocks power, Logic power and Signal powers are independent of the capacitance scaling while the frequency is constant. At the same time IOs power, Leakage power as well as the Junction temperature varies. Along with fixed 1GHz frequency it is found that there is 71.92% increment on IOs power while capacitance is incremented by 90%. At the same time there is a 2.4% increment found in Leakage power while Junction temperature faces an change of 7.14%.
