Abstract

In this work, we are using frequency scaling, toggle rate scaling and of POD IO standard to design and implement energy efficient 64-bit ALU on ultra scale FPGA. We have analyzed both static and dynamic power for three different toggle rate, three different frequencies, and three different POD IO standards. Scaling of toggle rate is directly proportional to dynamic power but it does not make any effect on static power. Scaling of frequency and changes in IO standards have the significant impact on both dynamic and static power. POD10 is the most energy efficient IO standard. Power is lowest when the device is operating on the lowest frequency of 0.1 GHz. When toggle rate is 3.125%, dynamic power is the lowest in comparison of 12.5% toggle rate. There is 81.55% power saving with POD10 IO standards along with 0.1 GHz frequency and the 3.125% toggle rate in comparison to POD12_DCI IO standards with the 10 GHz and 12.5% toggle rate. There is 63-80% saving in power with frequency scaling only.
