Abstract

Power dissipation is a dominant aspect that limits the performance of microprocessors. In this work adaptive supply and body voltage control is used by applying optimum Vdd and NMOS-PMOS body bias voltages (VBB-N & VBB-P) to the microprocessor unit, which compensate the threshold voltage and clock frequency for ultra-low power design. SPICE simulation measurements on a 22-nm technology are used to evaluate the theoretical basics and fundamentals. The results show that, optimal amount of power consumption and temperature reduction have been obtained for different workload and simulation environments.
