简介
Timing and synchronization play a key role in 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 application specific integrated circuits (ASICs) or field programmable gate arrays (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 …
