“…In [6], they introduce temperature-tracking based frequency scaling, localized toggling and computation migration to spare hardware units. In [7], they propose a hybrid DTM technique that combines fetch gating and DVS. In [8], they propose a formal feedback control theory and use DTM as a test vehicle.…”

In this paper, we propose an effective dynamic thermal management (DTM) scheme for MPEG-2 decoding by allowing some degree of spatiotemporal quality degradation. Given a target MPEG-2 decoding time, we dynamically select either an intraframe spatial degradation or an inter-frame temporal degradation strategy in order to make sure that the microprocessor chip will continue to stay in a thermally safe state of operation, albeit with certain amount of image/video quality loss. For our experiments, we use the MPEG-2 decoder program of MediaBench and modify/combine Wattch and HotSpot for the power and thermal simulations and measurements, respectively. Our experimental results show that we achieve thermally safe state with spatial quality degradation of 0.12 Root Mean Square Error (RMSE) and with frame drop rate of 12.5% on average.

“…Instead, packages are designed for worst typical behavior and rely on Dynamic Thermal Management (DTM) techniques to control the temperature. Many hardware and softwarebased DTM techniques have been proposed recently [3,6,7,12,13,15]. Most of them, with the exception of [15], are reactive in nature.…”

Power density has been increasing at an alarming rate in recent processor generations resulting in high on-chip temperature. Higher temperature results in poor reliability and increased leakage current. In this paper, we propose a temperature aware scheduling technique in the context of embedded multi-tasking systems. We observe that there is a high variability in the thermal properties of different embedded applications. We design temperature-aware scheduling (TAS) scheme that exploits this variability to maintain the system temperature below a desired level while satisfying a number of requirements such as throughput, fairness and real time constraints. Moreover, TAS enables exploration of the tradeoffs between throughput and fairness in temperature-constrained systems. Compared against standard schedulers with reactive hardware-level thermal management, TAS provides better throughput with negligible impact on fairness.

“…Skadron, et al suggested several schemes for the thermal management including temperature-tracking [11], hybrid scheme [9], and feedback control [10,8]. In [11], temperature-tracking scheme manages temperature based on frequency scaling, localized toggling, and computation migration.…”
