Timekeeping presents a particular challenge in this emerging field, which depends on precise knowledge of time in order to infer location, control communications and accurately coordinate activities in a broad and growing range of applications, from autonomous cars and aircraft autopilot systems to advanced robotic and medical devices, energy-efficient buildings and an array of other industrial initiatives.
"Through the Roseline project, we will drive cyber-physical systems research with a deeper understanding of time and its trade-offs, and advance the state-of-the-art in clocking circuits and platform architectures," Srivastava said.
Time has always been a critical issue for science and technology. From pendulums to atomic clocks, the accurate measurement of time has helped drive scientific discovery and engineering innovation. For example, advances in distributed clock synchronization technology enabled Global Positioning System (GPS) satellites to precisely measure distances. This, in turn, created new opportunities -- and even entirely new industries -- and led to the development of mobile navigation systems.
Still, many other areas of clock technology are still ripe for development, including CPS applications, which play a critical role in our physical and network infrastructure and need precise timekeeping to properly connect computers, communications technologies, sensors and actuators to objects and.
Over the five-year span funded by NSF, the Roseline team will rethink and reengineer how the knowledge of time is handled across a computing system's hardware and software. The group seeks to develop new clocking technologies, synchronization protocols and operating system methods, as well as control and sensing algorithms.
Project leaders also plan to integrate CPS and timing components into graduate and undergraduate course materials and engage in outreach efforts to pre-college students, including the
In addition to Srivastava and Pamarti, the Roseline team includes co-principal investigator
Roseline is a key component in the NSF's longstanding support for CPS research and education, an area in which the agency has invested nearly
"As computation becomes embedded in physical systems around us, it becomes all the more important that computers be able to know time accurately, efficiently and reliably," said
