The complexity of embedded computing systems is increasing at a rapid rate due to both advances in technology and the increasing demand for complex applications. A wide variety of these systems employ multi-core architectures to keep up with the demand for performance under stringent power and thermal constraints. Adaptation to the dynamic changes in the application is critical to improve overall performance, energy efficiency as well as reliability.Although dynamic adaptation (reconfiguration) techniques have received considerable attention from various domains, they are not employed in real-time System-on-Chip (SoC) designs. This is due to the fact that real-time systems may consist of critical tasks with soft or hard deadlines, and the dynamic reconfiguration overhead may adversely affect the critical tasks. Missing deadlines may lead to performance degradation or even catastrophic failures in these systems. The proposed research will develop automated tools and techniques to address three fundamental challenges in exploiting dynamic reconfigurations in real-time multitasking systems: i) lack of a comprehensive framework that can synergistically exploit the advantages of dynamic reconfiguration of computation, communication as well as storage, ii) lack of efficient real-time scheduling techniques in the presence of dynamic reconfigurations techniques, iii) lack of dynamic reconfiguration that considers a wide variety of design and optimization constraints. Rather than focusing on one optimization objective or specific domain, this research takes a comprehensive approach by considering synergistic effects of computation, communication as well as storage to optimize overall performance, energy and reliability without violating real-time constraints.This project will make significant broader impact in several fronts. The proposed approaches can enable a wide range of energy-efficient and low-cost embedded systems. Reduction in energy consumption directly relates to significant improvements in operating lifetime for battery powered mobile devices. Similarly, reduction in temperature improves system reliability. Embedded systems with dynamic reconfiguration capabilities will have two major impacts. One being low-cost and high-quality everyday appliances for the public, and the other is improved efficiency of safety-critical devices such as biomedical and military equipment.

由于技术的进步和对复杂应用的需求不断增长，嵌入式计算系统的复杂性正在以迅速的速度增加。各种各样的系统采用多核架构来跟上在严格的功率和热约束下对性能的需求。适应应用程序的动态变化对于提高整体性能，能源效率和可靠性至关重要。尽管动态适应（重新配置）技术已经从各个领域受到了极大的关注，但它们并未在实时的系统中使用。 （SOC）设计。这是由于实时系统可能包括具有软截止日期或硬期限的关键任务，而动态重新配置开销可能会对关键任务产生不利影响。缺少截止日期可能会导致这些系统中的性能退化甚至灾难性失败。拟议的研究将开发自动化工具和技术，以应对实时多任务系统中动态重新配置时的三个基本挑战：i）缺乏一个可以协同利用动态重新配置的计算，通信，以及既有的，又可以协同利用的综合框架，以及ii）在存在动态重新配置技术的情况下，缺乏有效的实时调度技术，iii）缺乏动态重新配置，从而考虑了各种各样的设计和优化约束。这项研究不是专注于一个优化目标或特定领域，而是通过考虑计算的协同效应，沟通以及存储以优化整体性能，能源和可靠性而不违反实时约束，从而采取了全面的方法。在几个方面的影响。所提出的方法可以实现广泛的节能和低成本嵌入式系统。能源消耗的降低直接涉及电池供电的移动设备的运营寿命的显着改善。同样，温度降低可提高系统的可靠性。具有动态重新配置功能的嵌入式系统将产生两个重大影响。 一个是公众的低成本和高质量的日常用具，另一个是生物医学和军事设备等安全至关重要设备的提高效率。
