摘要
从调度机制、信号量和消息队列3方面将Linux、RT-Linux和VxWorks进行了综合对比,并结合测试用例得出了影响Linux实时性能的瓶颈。最后从上述3方面给出了Linux实时性能改造的可行性办法。
The comparison of the overall performances among the Linux, RT-Linux and VxWorks is made through testing their schedulers, semaphores and message queues. The bottleneck problems affecting the real-time performance of the Linux are also discussed. Some feasible methods to improve the real-time performance of the Linux are presented.
