题目：基于模拟计算的实时全球电源管理：从设备到多核系统摘要：“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。”随着半导体技术进入纳米时代，现代超大规模集成电路系统面临着前所未有的功率危机。虽然现有的电源管理方法在许多IC模块中已经被证明是成功的，但随着结构和算法复杂性的不断增加，这些方法在速度、功耗和复杂性方面暴露出局限性。本项目将对电力计算、建模、管理和优化进行综合研究。通过开发多核系统的通用物理模型，该项目引入了使用模拟计算来解决多变量全局功率优化问题的概念。模拟计算提供了比数字计算更快、更准确、更实时的解决方案。提出了一种基于硬件的方法，通过多输出转换器的设计，与功率优化器协调工作，将转换器意识纳入电压/频率调度。对全局和转换器意识概念的进一步扩展导致了在单个硬件平台上具有泄漏意识的通用电源管理解决方案。本课题是多领域的融合，实现从器件到电路级的电源管理，最终实现系统级的电源优化。这一成果将惠及所有与电力相关的行业，包括封装、冷却和电池制造，并将导致一系列节能电子设备的新发明。PI提出了一个同步的综合教育计划，其中包括改进的VLSI设计和电源管理课程，引入工业辅导计划，包括本科生和研究生的参与，以及向代表性不足的群体伸出援手。该教育计划强调多样性，将产生巨大的社会效益。

Proposal ID: 0844557Title: Analog Computation Based Real-Time Global Power Management: from Devices to Multi-Core SystemsPI: Dongsheng MaInstitute: University of Arizona ABSTRACT"This award is funded under the American Recovery and Reinvestment Act of 2009(Public Law 111-5)."As semiconductor technology enters the nanometer regime, modern VLSI systems face an unprecedented power crisis. Although existing power management methods have proven to be successful in many IC modules, as structural and algorithmic complexity keep increasing, these methods expose the limitations in the aspects of speed, power consumption and complexity. This project is to conduct a comprehensive study on power computing, modeling, management and optimization. By developing a generic physical model for multi-core systems, the project introduces a concept of using analog computation to solve multi-variable global power optimization problems. Analog computation provides a much faster, more accurate, real-time solution than the digital counterparts. A hardware-based approach, through a multiple-output converter design, is proposed, which works harmoniously with the power optimizer to incorporate converter-consciousness into voltage/frequency scheduling. Further extension of global and converter-conscious concepts leads to a leakage-aware universal power management solution on a single hardware platform. This project is an assimilation of multiple domains, which achieves power management from the device, to the circuit level, eventually leading to system-level power optimization. The outcomes will benefit all power-related industries including packaging, cooling, and battery manufacture, and will lead to a series of new inventions of power-efficient electronic devices. The PI proposes a concurrent and integrated educational program that includes an improved VLSI design and power management curriculum, the introduction of an industrial tutoring program, the inclusion of undergraduate and graduate student involvement and the outreach to under-represented groups. The educational plan emphasizes diversity and will result in tremendous social benefits.
