Power Efficient Gurumukhi Unicode Reader Design and Implementation on FPGA

Gurumukhi is found to be the most widely used language of Pakistan, and it is ranked 3rd in Canada, 7th in India and almost 4th most spoken language in U.K. This Unicode Reader is cost effective solution for learning as well as understanding the Punjabi language by the people across the globe .This reader helps the user to understand, whether written text is consonants, vowels or digits of Gurumukhi scripts. This paper can also be the solution to the various problems occurred in research of Punjabi natural language processing. Hardware is designed for Gurumukhi Unicode Reader (GUR) and is implemented on Virtex-6 FPGA on Xilinx software. This GUR design is tested on different frequencies by applying frequency scaling techniques .The reader is also observed on different IO Standards of two logic families i.e. on SSTL (Stub-Series Terminated Logic) and LVDCI (Low Voltage Digitally Controlled Impedance) logic families to make this design more energy efficient. It is concluded that using LVDCI_DV2_15 rather than SSTL18_II_DCI, the total power can be saved up to 51.22% with the device operating at a frequency of 1MHz.
