Modeling and Improving Data Cache Reliability

Soft errors arising front energetic particle strikes pose a significant reliability concern for computing systems, especially for those running in noisy environments. Technology scaling and aggressive leakage control mechanisms make: the problem caused by these transient errors even snore severe. Therefore, it is very important to employ reliability enhancing mechanisms in processor/memory designs to protect them against soft errors. To do so, we first need to model soft errors, and their study cost/reliability tradeoffs among various reliability enhancing techniques based on tire model so that system requireirients could be met.
