The objective of this research is to investigate and create run-time adaptive error control methods for hybrid CMOS/nanoelectronics networks-on-chip. The approach is to exploit dynamic cooperation among layers in the on-chip network protocol stack, in order to adapt the error control to changing noise environments and achieve the required quality-of-service.Intellectual Merit: This research addresses the critical reliability problem of integrating deep nanometer CMOS and emerging nanoelectronics processing and storage elements on a single chip. These dissimilar cores communicate with one another over closely spaced unreliable interconnect links, requiring effective error control methods to improve link reliability at moderate energy and performance costs. The research will (i) investigate, analyze, and construct run-time adaptive cooperative error control methods that adjust the error control to channel conditions for average-case, rather than worst-case energy performance; (ii) develop models that accurately capture realistic traffic and system behaviors of these unique hybrid networks-on-chip; and (iii) demonstrate a reliable heterogeneous network-on-chip prototype.Broader Impacts: This project will accelerate realization of reliable low-cost energy-efficient heterogeneous systems-on-chip, potentially leading to societal and economic breakthroughs in biology, computing, communications, defense, and infrastructure monitoring. Knowledge acquired will be disseminated via workshops, lectures, and a public website. Further, the research will support development of a new course and the first textbook on the subject. Through the PI's already established community engagement and mentoring, this research will be used to inspire, recruit, and retain underrepresented students in engineering. Finally, ongoing international collaborations will enhance the research and global perspectives of US student participants.

本研究的目的是研究和创建混合CMOS/纳米电子网络芯片的运行时自适应误差控制方法。该方法是利用片上网络协议栈中的层之间的动态合作，以适应不断变化的噪声环境的错误控制，并实现所需的服务质量。智力优点：这项研究解决了关键的可靠性问题，集成深纳米CMOS和新兴的纳米电子处理和存储元件在一个单一的芯片上。这些不同的内核通过紧密间隔的不可靠互连链路相互通信，需要有效的错误控制方法来以适度的能量和性能成本提高链路可靠性。该研究将（i）调查、分析和构建运行时自适应协作差错控制方法，该方法根据信道条件调整差错控制，以实现平均情况而不是最坏情况的能量性能;（ii）开发能够准确捕获这些独特的混合片上网络的实际流量和系统行为的模型;（iii）演示可靠的异构片上网络原型。该项目将加速实现可靠的低成本节能异构片上系统，可能导致生物学，计算，通信，国防和基础设施监控方面的社会和经济突破。将通过讲习班、讲座和公共网站传播所获得的知识。此外，这项研究将支持开发一门新课程和关于这一主题的第一本教科书。通过PI已经建立的社区参与和指导，这项研究将用于激励，招聘和留住工程专业代表性不足的学生。最后，正在进行的国际合作将加强美国学生参与者的研究和全球视野。
