摘要
提出一种集成的实时资源管理和实时服务器技术 ,它对进程间通信和同步机制进行有效地管理 ;同时在两种技术的基础之上 ,构造了一个比较高效的优先级倒置问题的控制算法 ,克服了传统的用优先级继承方法来解决优先级倒置问题在最坏情况下延迟很大 ,而用优先级冲顶方法会引起低优先级进程阻塞的缺点 .通过这种机制 ,既可以使系统避免多重优先级倒置现象的发生 。
A technology for managing an integrated real-time resource and a real-time server was proposed. It managed interprocess communication and synchronization mechanisms effectively. It was an advanced algorithm for managing priority inversion based the technologies mentioned above. This could avoid the disadvantages caused by the traditional methods -priority inheritance and priority ceiling. The former had a longtime delay and the latter suspended the low-priority processes. The new mechanism could avoid nesting priority inversion, and make the behavior of the system analyzable and predictable.
