CSR: Small: Collaborative Research: Adaptive Applications and Architectures for Variation-Tolerant Systems

CSR：小型：合作研究：适应应用和结构的变化容忍系统该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。集成电路（IC）的纳米尺度给设计人员带来了新的挑战，其中最重要的是集成电路元件特性的变化。这些变化可能会削弱技术规模化带来的基本好处，比如每个晶体管的成本、性能和功耗的提高。到目前为止，已经提出的变化感知设计技术已经达到了极限，并且无法包含不断增加的变化。因此，为系统开发新的设计方法是很重要的，这些方法对底层组件的变化具有内在的弹性。该项目开发了一个基于自适应应用程序和架构的框架，用于设计可容忍变化的特定应用程序系统。它通过(i)在系统架构和应用层采用跨层方法，（ii）利用固有的“弹性”来推进最先进的技术。广泛的应用程序，以适应底层硬件的变化，同时仍然产生可接受的性能和维护最终用户体验，以及（iii）探索混合（设计时和制造后）设计方法，使系统适应更准确和有效的变化。发达的技术将大大扩展我们的能力，使我们能够在面对不断增加的变化时利用技术扩展的好处。更广泛的影响包括与半导体行业合作，验证和转让已开发的技术，将新的教育材料纳入SoC设计和嵌入式系统课程，以及本科设计项目。

CSR: Small: Collaborative Research: Adaptive Applications and Architectures for Variation-Tolerant SystemsThis award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The scaling of integrated circuits (ICs) into the nanometer regime has thrown up new challenges for designers, foremost among which are variations in the characteristics of IC components. Variations threaten to diminish the fundamental benefits of technology scaling, such as improvements in cost-per-transistor, performance and power consumption. Variation-aware design techniques that have been proposed thus far are being stretched to their limits, and cannot contain the incessant increase in variations. Therefore, it is important to develop new design approaches for systems that are inherently resilient to variations in the underlying components. This project develops a framework based on adaptive applications and architectures for the design of variation-tolerant application-specific systems. It advances the state-of-the-art by (i) adopting a cross-layer approach at the system architecture and application layers, (ii) leveraging the inherent ?elasticity? of a wide class of applications to adapt to variations in the underlying hardware while still producing acceptable performance and maintaining end-user experience, and (iii) exploring a hybrid (design-time and post-fabrication) design methodology, enabling more accurate and effective system adaptation in response to variations. The developed technologies will significantly extend our ability to avail of the benefits of technology scaling in the face of increasing variations.The efforts towards broader impact include working with the semiconductor industry to validate and transfer the developed technologies, new educational material incorporated in courses on SoC design and embedded systems, and undergraduate design projects.
