A 65-nm Mobile Multimedia Applications Processor with an Adaptive Power Management Scheme to Compensate for Variations

Abstract

In this paper we present the SmartReflex <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">™</sup> power management techniques implemented on the OMAP3430 Mobile Multimedia Applications Processor. By using multiple voltage domains, fine grain power domains, split-rail memories, and adaptive compensation, SoC active power reduction of 66% and leakage power reduction of 2~3 orders of magnitude was achieved. OMAP3430 contains more than 150M transistors.
