Abstract
Dynamic Thermal Management (DTM) techniques have been
proposed to save on thermal packaging and cooling costs for general-
purpose processors. However, when invoked, these techniques re-
sult in a significant performance degradation. This paper con-
cerns performance-effective DTM for multimedia applications. We
make two contributions: (1) Current DTM algorithms are reac-
tive in nature. We propose a predictive DTM algorithm targeted
at multimedia applications, which allows the efficient use of re-
sponse mechanisms that have high invocation overhead. We find
that for our applications, our predictive algorithm performs sig-
nificantly better than existing reactive DTM algorithms. (2) We
evaluate the effectiveness of different DTM response mechanisms.
Specifically, we demonstrate the importance of tailoring DTM re-
