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.

CSR：小型：协作研究：容变系统的自适应应用和架构该奖项由 2009 年美国复苏和再投资法案（公法 111-5）资助。给设计人员带来了新的挑战，其中最重要的是 IC 元件特性的变化。变化可能会削弱技术扩展的基本优势，例如每晶体管成本、性能和功耗的改进。迄今为止提出的变化感知设计技术已经达到了极限，并且无法遏制变化的不断增加。因此，为系统开发新的设计方法非常重要，这些方法对于底层组件的变化具有固有的弹性。该项目开发了一个基于自适应应用程序和架构的框架，用于设计容变的应用程序特定系统。它通过（i）在系统架构和应用程序层采用跨层方法，（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并保持最终用户体验，以及（iii）探索混合（设计时和制造后）设计方法，从而实现更准确和有效系统适应变化。面对日益增加的变化，所开发的技术将显着增强我们利用技术扩展优势的能力。争取更广泛影响的努力包括与半导体行业合作验证和转让所开发的技术、将新的教育材料纳入 SoC 课程设计和嵌入式系统以及本科设计项目。
