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。本研究的目的是将安全和时间作为主要考虑因素，重新设想计算机体系结构和网络算法，为CPS提供强大的基础。这种方法是重新考虑硬件和软件的划分，提供真正的进程并发和隔离。将这些好处扩展到通信网络，从而成为CPS的组成部分，将提出考虑CPS限制的组播和安全创新。本项目将通过以下任务为CPS提供计算和通信基础。(1)打造开源硬件设计。放弃了容易出错的共享内存通信模式，用于数据流计算的Precision Timed(Pret)处理器将得到扩展。(2)将专门针对PRET体系结构研究硬件/软件接口。(3)研究了一种考虑CPS约束的路由算法。约束包括效率、适应性、可伸缩性、简单性和安全性。(4)研究分布式信源编码在CPS应用中的应用，重点研究这些应用中小数据包大小带来的挑战。该项目将通过以下承诺，让社区和学生在多个年级和机构中参与。(1)将制定一套CPS的教育和研究方案。这套教材和本项目的教材将以教程、出版物和课程的形式提供给其他机构。(2)将研究成果与教育相结合，创建新课程。(3)将招收不同的学生群体，包括妇女和少数族裔。(4)在医疗器械和应急领域实施两项应用。

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.
