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.

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。如果不加以控制，这些变化需要不可接受的设计裕度，可能导致瞬时和永久性故障，并显着降低系统的可靠性和弹性。这个项目是考虑电子系统定期定期深度复兴的潜在变革概念，类似于生物系统在睡眠期间的恢复。到目前为止，电子设备的睡眠只是意味着一段不活动的时间;这个提议探讨了睡眠成为一个活跃的恢复期的想法，这对电子设备来说是必不可少的，就像在生物学中一样。这种深度恢复方案需要跨层优化，以平衡各种权衡。有希望的初步实验结果表明，拟议的活动的潜在好处。这项研究如果成功，可能会对半导体行业和整个社会产生深远的影响，影响电子系统的设计、使用和操作方式。由于周期性恢复，这样的系统可以被优化以运行更快、消耗更少的功率、具有更小的面积、成本更低，并且因此总体上每美元提供更多的价值。首席研究员计划开发一本用于特定应用集成电路或片上系统的教科书，该教科书将利用iBook格式所提供的交互式图形，并在现有在线讲座的帮助下“翻转”课堂。
