Design and realization of double message queue in interrupt management system forμC/OS-II system

The μC/OS-Ⅱ's portability is blocked seriously by non-interrupt management.To solve this problem,a standpoint of a interrupt management system(IMS) is proposed,which adds IMS into μ C/OS-Ⅱ.Double message queue for IMS(DMQIMS) is proposed.This IMS is divided into a critical part(CP) and a delayed part(DP) with hierarchical thinking.CP will be processed preferentially,which can meet the need of real-time performance;And DP achieves deferred processing mechanism,using the priority dual message.Experiments show that excellent real-time operating is showed in DMQIMS,and the real-time performance has increased by average 51%,which is compared to the same conditions Linux system.Finally,the DMIMS can also be used in industry or aviation and so on embedded system.
