CSR---EHS: Low Power, High Performance, Embedded Digital Feedback Control

该项目的目标是开发专门针对反馈数字(软件)控制器进行优化的新的嵌入式体系结构系列，目的是将所需功率降低一个数量级以上，并以目前软件无法实现的水平提供实时性能。这是通过利用反馈控制器特有的多种冗余来实现的，但这些冗余没有被任何当前的处理体系结构所利用。这项工作是与现场的微机电系统(MEMS)研究人员合作，为该环境下的软件控制开发实用的解决方案。这项工作的更广泛影响还包括开发适用于控制系统设计的更好的建筑设计指标，以及为低功率数字控制带来的好处开辟新的工程领域。由于这项工作的大部分可以在FPGA仿真中进行测试，我们计划让本科生参与多线程控制器软件的构建，以使用为这项工作开发的工具来测试这些想法。

This project has the goal of developing a new family of embedded architectures optimized specifically for feed-back digital (software) controllers, with the aim of decreasing the required power by more than an order of magnitude and delivering real-time performance at levels that currently cannot be achieved from software. This is done by exploiting many kinds of redundancies peculiar to feedback controllers but that are not exploited by any current processing architecture. The work is in collaboration with on-site micro-electro-mechanical systems (MEMS) researchers to develop practical solutions for software control in that environment. The broader impact of this work also includes the development of better architectural design metrics applicable to control system design as well as opening new engineering areas to the benefits of low-power digital control. Since much of this work can be tested in FPGA emulation, we plan to include the participation of undergraduates in the construction of multi-threaded controller software to test these ideas using tools developed for this work.
