摘要
本文主要探讨了在实时处理中,由于PC—DOS的不可重入性引起系统死锁的问题。实践证明,充分地保护好DOS现场;迂回判断DOS核心态标志;一次性部分重入等均为有效的解决方法。
The non-reenterability problem of PC-DOS met in the real-time processing is discussed. Several solving methods for this problem are explored. Such as fully keeping the DOS scene, tortuously judging the DOS core-state-flag, one-timely and partially reentering DOS and so on.
