Frequency scaling based low power ORIYA UNICODE READER (OUR) design ON 40nm and 28nm FPGA

Abstract

In the past, it was observed that at among all the 22 languages oriya script is also most vibrant and has been used across the entire country by Oriya community. Oriya Unicode reader is used for decoding the languages used in Indian states of Orissa. In our work we are implementing an energy efficient Oriya Unicode reader. This experiment is done on Xilinx 14.2 ISE Design Suit software for 28nm FPGA platform and results are being compared with 40nm FPGA. We have scaled the frequency of Unicode reader from 1THz to 1MHz. On comparison between 40nm and 28nm FPGA, it was observed that 28nm FPGA consumes least amount of power when operated at 1MHz-1THz frequency using SSTL18_I IO standard.
