Lifetime Reliability Aware MicroprocessorsAs CMOS scaling continues, increasingly smaller feature sizes and increasing power densities are accelerating the onset of wear-out or aging-related hard failures in processors. Current lower-level solution strategies will likely be inadequate to address this lifetime reliability problem. This research advocates higher-level, microarchitectural solutions for processor lifetime reliability. The first component of this work is in the development and validation of microarchitecture-level models, metrics, and tools that incorporate key failure mechanisms and their scaling behavior. The second component develops novel architectural solutions for the lifetime reliability problem, including dynamic reliability management and selective structural redundancy. The performance benefits from CMOS technology scaling over the last several decades have enabled the information revolution that has affected virtually every aspect of society. The problem of lifetime reliability addressed in this proposal is one of the key impediments to seeing continued benefits from CMOS scaling. The proposed work seeks to develop a fundamentally new approach to address this problem that will enable meeting the reliability goals critical for all processor manufacturers. This work is in collaboration with researchers from IBM which will provide needed industrial expertise as well as a path for technology transfer.

具有终生可靠性意识的微处理器随着 CMOS 尺寸的不断缩小，越来越小的特征尺寸和不断增加的功率密度正在加速处理器中磨损或与老化相关的硬故障的发生。 当前的较低级别的解决方案策略可能不足以解决此寿命可靠性问题。这项研究提倡采用更高级别的微架构解决方案来提高处理器生命周期的可靠性。这项工作的第一个组成部分是开发和验证包含关键故障机制及其扩展行为的微架构级模型、指标和工具。第二个组件为生命周期可靠性问题开发新颖的架构解决方案，包括动态可靠性管理和选择性结构冗余。过去几十年来，CMOS 技术扩展带来的性能优势促成了信息革命，几乎影响了社会的各个方面。该提案中解决的寿命可靠性问题是从 CMOS 微缩中获得持续优势的主要障碍之一。拟议的工作旨在开发一种全新的方法来解决这个问题，从而实现对所有处理器制造商至关重要的可靠性目标。这项工作是与 IBM 的研究人员合作进行的，IBM 将提供所需的行业专业知识以及技术转让途径。
