| 摘 要： | 通过对一个嵌入式实时操作系统（ARTs-OS）的研究,介绍了减少中断延迟的具体方法.中断模拟是RT-Linux中采用的减少中断延迟的方法,解决中断延迟的另一种方法是使用中断嵌套,这两种方法各有优缺点.在分析RT-Linux方法和VxWorks方法优劣的基础上,提出了ARTs-OS中断调度模型.针对ARTs-OS的中断调度模型,给出了其算法实现及这种算法的性能分析.在Pentium166MHZ机上的测试数据和性能评价结果表明,ARTs-OS采用的方法是可行的. |

| Abstract: | Via the research of ARTs-OS, the methods to reduce interrupt delay are introduced. There are two interrupt dispatch models to reduce interrupt delay, that are interrupt emulation adopted in RT-Linux and nested interrupt. These two methods have their own advantages and defects. On the basis of comparing interrupting technology of RT-Linux and VxWorks resolution, the interrupt dispatch model for ARTs-OS is given. The algorithm realization and its performance evaluation of the interrupt dispatch model for ARTs-OS are discussed in detail, Experimental results on Pentium 166 MHZ show effectiveness of the solution. |
| Keywords: | micro-kernel embedded real-time operating system interrupt emulation interrupt dispatch interrupt dispatch model |
