随着麒麟操作系统在实时数据处理领域得到广泛的应用，对其实时性能的掌握显得尤为重要。对麒麟操作系统的实时性进行研究分析，提出了一种测试操作系统整体实时性能的方法，利用时统中断卡从外部产生中断来触发任务执行，通过衡量从中断产生到任务执行的任务响应时间，分别对系统标准版和实时版的实时性能进行了测试。测试结果表明，该方法能够对系统整体实时性能做出准确评价，适用于麒麟操作系统的实时性能测试。%With the KYLIN operating system is widely used in the field of real -time data processing , it is particularly important to grasp its real -time performance .The article researched the real -time property of the KYLIN operating system .It put forward a method to test the overall real -time performance of the operating sys-tem.We used the timing system interrupt card to interrupt from the external in order to trigger the task execution and tested real-time operating system and the standard operating system respectively by measuring the task re-sponse time that is from the interrupt generation to the task execution .Test results showed that the method can accurately evaluate the overall real -time performance of the system , and it is suitable for the real -time per-formance test of the KYLIN operating system .
