Abstract :
In this paper we present the SmartReflextrade 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.
