CLASH - Cross-Layer Accelerated Self-Healing: Circadian Rythms for Resilient Electronic Systems

未来电子系统面临的一个巨大挑战是处理工艺、电压、温度和老化变化。如果不加以检查，这些变化需要不可接受的设计余量，可能导致暂时和永久的故障，并显著降低系统的可靠性和弹性。这个项目将考虑一个潜在的变革概念，即电子系统的定期深度恢复，类似于生物系统在睡眠期间的恢复。到目前为止，电子产品的睡眠只是意味着一段时间的不活动；这一提议探讨了睡眠对电子设备和生物学一样重要的积极恢复期的观点。这种深层再生方案需要跨层优化，以平衡各种权衡。有希望的初步实验结果显示了拟议活动的潜在效益。这项研究如果成功，将通过电子系统的设计、使用和操作方式，对半导体行业和整个社会产生深远的影响。由于定期更新，这些系统可以优化运行速度更快，功耗更低，面积更小，成本更低，从而总体上提供更高的每美元价值。首席研究员计划开发一本针对特定应用的集成电路或片上系统的教科书，它将利用iBook格式可能实现的交互式图形，并在可用的在线课程的帮助下“翻转”课堂。

A great challenge for future electronic systems is coping with process, voltage, temperature and aging variations. If left unchecked these variations require unacceptable design margins, can lead to transient and permanent faults, and significantly degrade the system reliability and resilience. This project is to consider the potentially transformative concept of regular periodic deep rejuvenation for electronic systems akin to the recovery during sleep for biological systems. Until now sleep for electronics just meant a period of inactivity; this proposal explores the idea of sleep becoming an active recovery period as essential for electronics as it is in biology. Such deep rejuvenation schemes will require cross-layer optimizations in order to balance the various tradeoffs. Promising preliminary experimental results show the potential benefits of the proposed activities. The proposed research, if successful, could have a deep impact on the semiconductor industry, and society as a whole, by the way electronic systems are designed, used and operated. Due to the periodic rejuvenation such systems could be optimized to run faster, consume less power, have less area, cost less, and thus overall provide more value per dollar. The Principle Investigator plans to develop a textbook for application-specific integrated circuits or systems-on-chips that would take advantage of the interactive graphics made possible by the iBook format, and to "flip" the classroom with the help of the available on-line lectures.
