摘要
为了提高Linux操作系统的实时性,研究了Linux操作系统System V信号量机制在内核中的实现,发现其在实时应用中存在的不足,提出并实现了一种对其进行改进的方法。经测试表明,采用该方法后可以明显降低实时进程申请信号量的延迟时间,说明该方法有效提高了Linux操作系统的实时性能。
In order to improve the real-time performance of the Linux operating system .This paper studies the realization of System V semaphore mechanism in Linux kernel , and found the deficiency when it used in real-time applications , then put forward a method to improve it .In the test we found that the delay time a real-time process ask for a semaphore is reduced obviously. It says that the method we used improves the real-time performance of Linux operating system efficient.
