System and Architectural Level Power Estimation, Optimization and Management

该项目研究了广义任务流图中计算和通信进程的同时调度和硬件/软件映射问题，以便在满足给定的截止期的情况下最小化目标系统的能量消耗。该项目还研究了与行为和RT级别的功耗分析和优化相关的一些问题，包括功耗建模和知识产权内核的表征，以及自动时钟门控。最后，该项目开发了动态电源管理算法，该算法通过关闭空闲设备或降低未充分利用的设备的速度来节省电能，并针对操作系统(OS)指导的电源管理以及各种系统模型下的动态电压和频率调节开发了最优策略

This project investigates the problem of simultaneous scheduling and HW/SW mapping of the computational and communication processes in a generalized task flow graph so as to minimize the energy dissipation of the target system while satisfying a given deadline. This project also studies a number of problems related to power analysis and optimization at the behavioral and RT levels, including power modeling and characterization of Intellectual Property cores, and automatic clock gating. Finally, the project develops dynamic power management algorithms, which save power by shutting down idle devices or slowing down underutilized devices, and develops optimal policies for operating system (OS) directed power management and dynamic voltage and frequency scaling under a variety of system models
