| Abstract: | This paper discusses the generation method of hardware interruption in Windows operation system. The designed interruption service procedure is tested in various time sequences by using hardware DIO output card, and the interference test is carried out when interruption service works in Windows system. Multiple test methods within the interruption threads and work threads are proposed, the required time of imple,nenting the relevant code segment by kernel level scheduling in Windows system is studied intensively, the accuracy of multiple timers is tested, and the interruption service procedure is designed for engineering purpose. |
