HSTL IO Standard Based Energy Efficient Multiplier Design using Nikhilam Navatashcaramam Dashatah on 28nm FPGA

In this paper we have designed an energy efficient multiplier using Nikhilam Navatashcaramam Dashatah Vedic technique. Vedic mathematics consists of 16 sutras and these sutras were used by our ancient scholars for doing there calculation faster, when there were no computers and calculators. Nikhilam Navatasaman is a Sanskrit word which menas “all from 9 and the last from 10”. In today’s work the demand is high speed, efficiency and should take lesser time. Appling these Vedic techniques reduces the system complexity, execution time, area, power and is stable and hence is efficient method. In this paper we have designed an energy efficient multiplier that consists of three inputs and one output. The temperature has been kept constant that is 25 degree Celsius. Airflow has been kept 250 LFM and medium Heat sink. IO Standards has been varied in order to achieve an energy efficient device. In this paper we have taken HSTL (High Speed Transceiver Logic) IOSTANDARD. In order to achieve speed and high performance in addition to energy efficiency, HSTL IO standard is used. HSTL family consists of HSTL _I, HSTL_II, HSTL_I_18 and HSTL_II_18, HSTL_I_12 and the analysis has been done on these IO standards. Frequency scaling is one of the best energy efficient techniques for FPGA based VLSI design and is used in this paper. At the end we can conclude that we can conclude that there is 23-40% saving of total power dissipation by using SSTL IO standard at 25 degree Celsius. The main reason for power consumption is leakage power at different IO Standards and at different frequencies. In this research work only FPGA work has been performed not ultra scale FPGA.
