Research Initiation Award: QoS-Aware Energy Management for Sustainable Real-Time Embedded Systems

研究启动奖为历史上黑人学院和大学的初级和中级职业教师提供支持，他们正在建立新的研究项目或重新定向和重建现有的研究项目。预计该奖项将有助于进一步提高教师的研究能力和效率，改善家庭机构的研究和教学，并使本科生参与研究经验。授予西弗吉尼亚州立大学的奖项在许多领域都有潜在的更广泛的影响。该项目的目标是为实时嵌入式系统（RTES）确定一个统一的电源管理解决方案，以最大限度地降低ES能耗，同时满足服务质量（QoS）约束和系统可靠性要求。本科生将获得研究经验。在这个项目中，传统的实时调度技术被用来创建一个调度框架，在设计节能的嵌入式系统，利用现代电源管理功能，而不牺牲系统性能。三个具体目标是：开发节能的调度算法，可以降低能耗的弱硬实时嵌入式系统，同时保持系统的可靠性;开发算法，以创建一个调度框架，可以最大限度地提高可靠的RTES在硬能源预算约束的QoS;并将此调度框架扩展到多核平台。该项目的新特点是将RTES设计的三个关键维度-能源效率，服务质量和可靠性-结合到一个单一的统一框架中，以从系统级别降低实时嵌入式系统的能耗。这一发现将改变嵌入式系统的设计方式，使其能够满足绿色和可持续计算平台的性能要求。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的知识价值和更广泛的影响审查标准进行评估来支持。

Research Initiation Awards provide support for junior and mid-career faculty at Historically Black Colleges and Universities who are building new research programs or redirecting and rebuilding existing research programs. It is expected that the award helps to further the faculty member's research capability and effectiveness, improves research and teaching at the home institution, and involves undergraduate students in research experiences. The award to West Virginia State University has potential broader impacts in a number of areas. The goal of the project is identify a unified power management solution for real-time embedded systems (RTES) in order to maximally lower ES energy consumption while satisfying the quality of service (QoS) constraint and system reliability requirements. Undergraduate students will gain research experiences. In this project, traditional real-time scheduling technology is leveraged to create a scheduling framework in the design of energy-efficient embedded systems, exploiting modern power-management features without sacrificing system performance. Three specific aims are to: develop energy-efficient scheduling algorithms that can reduce energy consumption for weakly hard real-time embedded systems while preserving the system reliability; develop algorithms to create a scheduling framework that can maximize the QoS for reliable RTES under hard energy budget constraint; and extend this scheduling framework to multicore platforms. The novel feature of the project is the combination of the three critical dimensions of RTES design - energy efficiency, quality of service, and reliability - into a single, unified framework to reduce energy consumption of real-time embedded systems from the system level. The findings will shift how embedded systems are designed to be able to meet performance demands on a green and sustainable computing platform.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
