In order to cope with time-varying input characteristics and demand for upgradability in new-generation communication systems and multimedia applications, embedded systems are being driven to provide tremendous flexibility through extensive configurations. Hence, along with performance, power, and reliability requirements, embedded systems now require hardware reconfiguration and self-adaptive system methodologies. In order to provide an effective, affordable, and seamless (from the application layer) transition from one configuration to another, system synthesis plays a crucial role. To achieve this, there is a need for the right balance between static compilation and dynamic configuration management. This project develops adaptivity-driven system synthesis tools coupled with a dynamic configuration management layer for adaptive embedded system with hardware configuration support. The research focuses on design of novel algorithms and optimization methods for design tools supporting self-adaptive systems. This project 1) develops holistic task scheduling and resource management methods which are adaptive-aware and consider the reconfiguration overhead, 2)develops system level layout planning for resource upgradability and configuration sequence awareness, and 3)develops efficient dynamic design making methods for configuration management layer which evokes the right configuration based on the current system state. The broader impact of this research is that the developed design tools can be deployed in future self-adaptive systems for software-defined radio and multimedia applications where programmability and flexibility are as crucial as computation power. The PI plans to develop new courses, recruit under-represented groups into her research, and facilitate outreach to other researchers and industry by providing online access to the developed design tools.

为了科普时变输入特性和新一代通信系统和多媒体应用对可重构性的需求，嵌入式系统正被驱动以通过广泛的配置提供巨大的灵活性。 因此，沿着对性能、功耗和可靠性的要求，嵌入式系统现在需要硬件重新配置和自适应系统方法。为了提供从一种配置到另一种配置的有效的、可负担的和无缝的（从应用层）过渡，系统综合起着至关重要的作用。 为了实现这一点，需要在静态编译和动态配置管理之间保持适当的平衡。本计画针对具有硬体组态支援的自适应嵌入式系统，开发一个具有动态组态管理层的自适应驱动系统综合工具。研究的重点是设计新的算法和优化方法的设计工具，支持自适应系统。该项目1）开发整体任务调度和资源管理方法，这些方法是自适应的，并考虑到重构开销，2）开发系统级布局规划，以实现资源可配置性和配置顺序意识，3）开发有效的动态设计方法，用于配置管理层，根据当前系统状态调用正确的配置。这项研究的更广泛的影响是，开发的设计工具可以部署在未来的自适应系统的软件定义无线电和多媒体应用程序的可编程性和灵活性是至关重要的计算能力。PI计划开发新课程，招募代表性不足的群体参与她的研究，并通过提供对开发的设计工具的在线访问来促进与其他研究人员和行业的联系。
