分析了32位Windows系统实现硬件中断服务的内部机理和系统对中断信号的响应性能，通过比较多种测试环境下得到的中断延时，讨论了中断频率、中断方式、调度方式等因素对Windows硬件中断实时响应性能的影响.指出在32位Windows系统中断延时不可避免的情况下，采用非共享式中断，以及合适的调度方法，可以相对减少中断延时，提高硬件中断的实时响应性能.
- Abstract:
-
The internal mechanism of hardware interrupt service implementation and the response performance of the system to interrupt signal of 32-bit Windows system are analyzed, and the influence of interrupt frequency, interrupt mode, scheduling mode and other factors on the real-time response performance of Windows hardware interrupt is discussed by comparing the interrupt delay obtained in various test environments. It is pointed out that in the case of unavoidable interrupt delay in 32-bit Windows system, the use of non-shared interrupt and appropriate scheduling methods can relatively reduce the interrupt delay and improve the real-time response performance of hardware interrupts.
