CSR: Small: Collaborative Research: Application-Aware Many-Core Virtualization for Real-Time Embedded Computing

半导体技术的不断进步使得将数百个处理核心集成到一个硅芯片中成为可能。然而，随着晶体管尺寸的不断缩小，越来越多的制造缺陷导致了严重的成品率损失，使芯片产品？利润将大幅下降。工艺变化也会导致芯片之间的性能和功耗特性有很大差异。此外，这种不确定性极大地加剧了开发、验证和维护基于这些芯片的软件的复杂性，特别是对于任务关键型实时嵌入式应用程序。该项目探讨了这样一种假设，即架构虚拟化是一种有效的策略，并将成为解决多核平台上广泛的流程变化和制造缺陷问题的标准。这项合作研究旨在开发有效的方法和技术来虚拟化多核平台上的硬件资源，从而在不改变操作系统和应用软件的情况下隔离底层硬件的不确定性。该项目旨在提高多核平台上开发的软件和系统的健壮性和可靠性。研究中开发的技术还可能有助于解决组件升级和过时问题，这是几十年来一直挑战军事和航空电子工业的问题。私人投资机构与其国际合作者之间的合作为建立国际研究和教育合作结构、分享研究专业知识、增加教育机会和促进文化交流提供了独特的机会。此外，该项目提供了培养、鼓励和吸引来自代表性不足群体的学生从事这项令人兴奋的研究的机会。

Continued advancements in semiconductor technology make it possible to integrate hundreds of processing cores into one silicon die. However, as the transistor size continues to shrink, increasing manufacturing defects have resulted in severe yield loss and made chip products? profit to drop substantially. Process variations also cause the performance and power characteristics differ significantly from chip to chip. In addition, this non-determinism greatly exacerbates the complexity of developing, validating, and maintaining software built upon these chips, especially for mission-critical real-time embedded applications. This project explores the hypothesis that architectural virtualization is an effective strategy and will be the norm to address extensive process variations and manufacturing defect problems on many-core platforms. This collaborative research effort seeks to develop effective methods and techniques to virtualize hardware resources on many-core platform and thus isolate the underlying hardware non-determinisms without changing the operating system and application software.This project seeks to improve the robustness and reliability of software and systems developed on many-core platforms. Techniques developed in the research may also help to address the component upgrade and obsolescence issue, which has been challenging military and avionics industry for decades. The collaborations between PIs and their international collaborators provide a unique opportunity to build an international research and educational collaboration structure, to share research expertise, to enhance the educational opportunity, and to promote cultural exchange. In addition, this project provides opportunity to nurture, encourage and attract students from under-represented groups to engage in this exciting research.
