This project, designing, implementing, and simulating architectural components to calculate their power requirements and developing detailed models of fault-tolerance, aims at acquiring appropriate infrastructure for the tasks (high-performance Blades, hard drive, Gigabit Ethernet, software). Proposing a shift in the design of embedded systems and microarchitectures, the work focuses on designing embedded systems that exploit application tolerance to reduced accuracy. Tolerance is often used to accommodate variations in quality of service in communication and network performance. While proposing a set of static and dynamic mechanisms to track computations involving control, the project pushes this tolerance into microarchitecture of embedded processors. The project examines two types of errors that benefit from tracking the data categories by evaluating the potential of mapping computations and data to -Architectural components with differing levels of soft error protection and-Reduced precision components, that save power through voltage overscaling and/or power gating. Proposed are a general compiler and architecture mechanisms that will function on any code, but are designed to exploit applications that can trade some form of output fidelity for relaxed accuracy requirements.

该项目设计、实施和模拟体系结构组件以计算其功率需求并开发详细的容错模型，旨在为任务(高性能刀片式服务器、硬盘驱动器、千兆以太网、软件)获取合适的基础设施。这项工作提出了嵌入式系统和微体系结构设计的转变，重点是设计利用应用程序容错来降低精度的嵌入式系统。容差通常用于适应通信和网络性能中服务质量的变化。在提出一套静态和动态机制来跟踪涉及控制的计算的同时，该项目将这种容错引入到嵌入式处理器的微体系结构中。该项目通过评估将计算和数据映射到具有不同软错误保护级别和降低精度的组件的体系结构组件的潜力，研究了从跟踪数据类别中受益的两种错误类型，这些组件通过电压超标和/或功率门控来节省电力。提出了一种通用的编译器和体系结构机制，可以在任何代码上运行，但被设计为利用可以用某种形式的输出保真度来换取宽松的准确性要求的应用程序。
