摘要 操作系统中时间车轮算法被广泛应用,不过其最大调度时间有限,分层时间车轮算法也存在着算法复杂的不足,在二者基础上提出了对时间车轮的改进方法。该算法不但消除了时间车轮计时时限的缺点,而且比分层时间车轮在算法上简单很多,很适用于程序存储空间紧张的嵌入式实时系统。 In the operating system, the time wheel algorithm is widely applied. But its biggest dispatch time is limited. The lamination time wheel algorithm also has the algorithm complex insufficiency. This article proposes the time wheel' s corrective method based on that. This algorithm does not only eliminate the time wheel's time limitation, it is also easier than score strata time wheel algorithm. It is suitable for the procedure storage space tense embedded real time system.
