CAREER: Performance Analysis and Tradeoff for System-Level Design Exploration of Real-Time Embedded Systems

本研究的目标是开发设计实时嵌入式系统的方法和工具，提供一个工具环境，帮助设计师探索广阔的设计空间，找到更好的系统架构配置。该方法是在系统级或处理器级的抽象上工作，并将问题表述为一个多属性优化问题，该问题捕获了系统设计中的各种质量需求。具体讨论的主题有：1。通过研究系统配置在时序规范方面的灵活性来评估时序性能，并制定评估系统灵活性的指标。2. 开发一个接口工具，以帮助系统开发人员指定价值功能和偏好。3. 将不精确多属性效用理论与进化算法相结合，寻找多目标优化问题的最优解。

This research is on developing methodologies and tools for designing real-time embedded systems with the goal of providing a tool environment to help designers explore a vast design space and locate superior system architectural configurations. The approach is to work at the system level or processor level of abstraction and to formulate the problem as a multi-attribute optimization one which captures various quality requirements in system design. Specific topics being addressed are: 1. Evaluating timing performance through studying the flexibility of a system configuration with respect to timing specifications, and formulating metrics for estimating the flexibility of systems. 2. Developing an interface tool for assisting system developers to specify value functions and preferences. 3. Combining the imprecisely specified multi-attribute utility theory with evolutionary algorithms to find optimal solutions for multiple objective optimization problems.
