CPS: Small: RUI: CPS Foundations in Computation and Communication

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，这项研究的目标是考虑安全和时间作为主要关注点，重新设想计算机体系结构和网络算法，为CPS提供一个强大的基础。 这种方法重新考虑了硬件和软件的划分，提供了真正的进程并发和隔离。 将这些好处扩展到通信网络，使其成为CPS的一部分，将提出考虑CPS约束的多播和安全创新。本项目将通过以下任务为CPS提供计算和通信基础。 (1)将创建一个开源硬件设计。 放弃共享存储器通信的易出错范例，用于并行计算的精确定时（PRET）处理器将得到扩展。 (2)硬件/软件接口将专门针对PRET架构进行研究。 (3)一个路由算法考虑CPS的约束将进行研究。 约束包括效率、适应性、可伸缩性、简单性和安全性。 (4)CPS应用的分布式信源编码将重点研究这些应用中的小数据包大小的挑战。该项目将通过以下活动，让社区和多个年级和机构的学生参与进来。(1)将汇编一套CPS教育和研究方案。这套教材和本项目的材料将以教程、出版物和课程的形式提供给其他机构。 (2)将创建新的课程，将研究成果融入教育。 (3)将招收包括妇女和少数民族在内的各种学生。 (4)将在医疗器械和应急响应领域实施两项应用。

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)The objective of this research is considering security and timing as primary concerns, re-envisioning computer architecture and network algorithms to provide a robust foundation for CPS. The approach is rethinking the hardware and software divide, providing true process concurrency and isolation. Extending these benefits to the communication network so integral to CPS, multicast and security innovations that consider CPS constraints will be proposed.This project will provide computational and communication foundations for CPS through the following tasks. (1) An open source hardware design will be created. Abandoning the error-prone paradigm of shared memory communication, Precision Timed (PRET) processors for dataflow computations will be extended. (2) The hardware/software interface will be investigated specifically for PRET architectures. (3) A routing algorithm considering the CPS constraints will be investigated. The constraints include efficiency, adaptability, scalability, simplicity, and security. (4) Distributed Source Coding for CPS applications will be studied with focus on challenges from small packet sizes in these applications. This project will engage the community and students in multiple grades and institutions, through the following undertakings. (1) A package for education and research in CPS will be assembled. This package and the material from this project in the form of tutorials, publications, and curriculum will be available to other institutions. (2) New courses will be created integrating research results into education. (3) A diverse group of students including women and minorities will be recruited. (4) Two applications will be implemented in the fields of medical devices and emergency response.
