Proposal ID: CCF-0542644 PI: Marculescu, Diana Institution: Carnegie-Mellon University Title: SGER: Analysis of Fault-Tolerant Nanoscale Designs ABSTRACT:Nano-scale computing for either CMOS or non-CMOS technology is widely agreed to be characterized by non-deterministic and unreliable behavior. While fault-tolerant computing is a mature area of research, automatically designing reliable systems out of unreliable components has proven to be a challenging task. Since a practical solution to synthesizing in an automated manner, nano-scale designs that are inherently fault-tolerant has yet to be found, theoretical bounds may offer a good insight into the achievable limits of error-resilience and required minimum redundancy (or extra logic) needed. This research is intended to fill this gap and is poised to have broader impact on possible novel modeling, design and system architecture concepts involved in silicon nano-electronics and beyond (SNB). One can envision applicability of the proposed modeling techniques to atomic scale DNA-based switches. The combination of the properties of nucleic acid with those of the metal ions can lead to chemically or physically activated switches that can be combined to achieve certain functionalities or to perform relatively complex Boolean functions. Since such switches are not perfect and redundancy use is mandatory for achieving reliable global switching behavior, determining a priori theoretical bounds for the necessary redundancy is of chief practical interest. Potential applications of these structures are in molecular electronics that might be used in human body-implanted sensors and actuators or non-invasive drug delivery systems.

提案ID：CCF-0542644 PI：Marculescu，Diana机构：卡内基梅隆大学标题：SGER：容错纳米级设计分析 摘要：CMOS或非CMOS技术的纳米级计算被广泛认为具有不确定性和不可靠性。虽然容错计算是一个成熟的研究领域，但从不可靠的组件中自动设计可靠的系统已被证明是一项具有挑战性的任务。由于一个实际的解决方案，以自动化的方式合成，纳米级的设计，固有的容错尚未找到，理论界可能会提供一个很好的洞察可实现的极限的错误弹性和所需的最小冗余（或额外的逻辑）。这项研究旨在填补这一空白，并准备对硅纳米电子学及其他领域（SNB）可能涉及的新建模，设计和系统架构概念产生更广泛的影响。人们可以设想所提出的建模技术的适用性，以原子尺度的DNA为基础的开关。核酸的性质与金属离子的性质的组合可以导致化学或物理激活的开关，其可以组合以实现某些功能或执行相对复杂的布尔函数。 由于这样的开关是不完美的，冗余的使用是强制性的，以实现可靠的全球切换行为，确定先验的理论界所需的冗余是主要的实际利益。这些结构的潜在应用是在分子电子学中，可能用于人体植入的传感器和致动器或非侵入性药物输送系统。
