This paper exploits the inherent redundancy available in wireless multimedia systems to tradeoff system redundancy versus power consumption. It is shown that aggressive power management techniques result in hardware failures that are mostly localized to embedded memories. By isolating these errors and utilizing system level fault tolerance techniques, we show that a reduction in power of up to 38% is possible in an H.264 decoder. This is coupled with a reduction of up to 20% in the underlying 3GPP WCDMA modem.
