Temperature Reduction Analysis in Sentry Tag Cache Systems

摘要

Power and temperature management continue to impose challenging issues in high-performance processor design. Processor power density is growing and has made building efficient cooling systems expensive. While Dynamic Thermal Management (DTM) techniques aim at reducing cooling systems cost, previously suggested low-temperature design could potentially provide further temperature reductions or help DTM operate more effectively.rnDifferent processor components have different levels of impact on the overall temperature. Meantime, reducing the temperature of different processor components could result in both transient and steady temperature changes.rnIn this paper, we study the temperature impact of exploiting Sentry Tag caches on cache temperature. We show that by using the Sentry Tag it is possible to reduce cache temperature effectively. In addition, we show that using Sentry Tag can impact transient temperature behavior which in turn enhances DTM efficiency.
