Abstract

Timing and synchronization play a key role in advanced cyber-physical systems (CPS). Precise timing, as often required in safety-critical CPS, depends on hardware support for enforcement of periodic measure, compute, and actuate cycles. For general CPS, designers use a combination of ASICs or FPGAs and conventional microprocessors. Microprocessors as well as commonly used computer languages and operating systems are essentially devoid of any explicit support for precise timing and synchronization. Modern computer science and microprocessor design has effectively removed time from the abstractions used by designers with the result that time is regarded as a performance metric rather than a correctness specification or criterion.There are interesting proposals and avenues of research to correct this situation, but the barrier is quite high for conducting proof of concept studies or collaborative research and development. This paper proposes a conceptual design and use model for a reconfigurable testbed designed specifically to support exploratory research, proof of concept, and collaborative work to introduce explicit support for time and synchronization in microprocessors, reconfigurable fabrics, language and design system architecture for time-sensitive CPS.
