SGER: Analysis of Fault-Tolerant Nanoscale Designs

提案ID：CCF-0542644 PI：Marculescu，Diana Institution：Carnegie-Mellon University标题：SGER：容错纳米级设计分析摘要：针对cmos或非cmos技术的纳米级计算被广泛认为具有不确定和不可靠行为的特征。虽然容错计算是一个成熟的研究领域，但事实证明，从不可靠的组件中自动设计可靠的系统是一项具有挑战性的任务。由于还没有找到以自动方式进行合成的实用解决方案，因此本质上具有容错能力的纳米级设计还没有找到，理论界限可能提供了对可实现的容错极限和所需的最小冗余(或额外逻辑)的良好洞察。这项研究旨在填补这一空白，并有望对硅纳米电子及以后(SNB)可能涉及的新颖建模、设计和系统架构概念产生更广泛的影响。人们可以想象所提出的建模技术对基于原子尺度DNA的开关的适用性。将核酸的性质与金属离子的性质结合起来，可以产生化学或物理激活的开关，这些开关可以组合起来实现某些功能或执行相对复杂的布尔函数。由于此类交换机并不完美，而且为了实现可靠的全局交换行为，使用冗余是强制性的，因此确定必要冗余的先验理论界限具有重要的实际意义。这些结构的潜在应用是分子电子学，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。

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.
