In this paper we focus on dynamic thermal management (DTM) strategies that use dynamic
voltage scaling (DVS) for power control. We perform a theoretical analysis targeted
atestimating the optimal strategy, and show two facts:(1) whenthere is a gap between the
initial and the limit temperatures, it is best to start with a high (though not necessarily
maximal) frequency and decrease it exponentially until the limit temperatureis reached;(2)
when being close to the limit temperature, the best strategy is to stay there. We use the …

We use the patterns exhibitedby the optimal strategy in order to analyze some existing DTMtechniques.
