Multiplier is an important hardware core for scientific computing.To validate the power dissipation differences of two kinds of multipliers (Serial,Pipeline),we took advantage of three kinds of skills to analyze their power consumption,including PowerPlay Power Analyzer Tool,the FPGA power consumption estimating formula applied by Altera,and the DC synthesis tool of Synopsys.Under our verification in condition of same calculating data width and working frequency,the results show that (1) the delay of pipeline multiplier is 38.5% of serial multiplier for the reason of parallel;(2) the pipeline multiplier takes 1.76 times ALUs than serial one.Our power dissipation analysis conclusions show that (1) there is no clear difference by PowerPlay Power Analyzer Tool;(2) we grasped serial multiplier takes 36% of power consumption of pipeline one through both the estimating formula and DC synthesis tool.
