Abstract
Cyber Physical Systems (CPS) combines physical and computing systems tightly. Node operating systems (OS) are fundamental units in CPS. There are still many problems unsolved when designing CPS especially CPS node OS in aspects of predictability, reliability, robustness, etc. Aiming at the problem, this paper proposes the effective shortest time priority algorithm and the adaptive shortest time priority algorithm. Experimental results show that, compared with the traditional FIFO (advanced first in first out) and LSF (least slack first) algorithm, the algorithm proposed in this paper effectively reduce the deadline miss ratio, as a result, the real-time performance of the CPS are effectively improved.
