Win9x下一种减小中断延时的软件模型

A software model for reducing latency based on Win9x environment

在论述Win9x的中断处理机制的基础上 ,分析了影响中断延时的关键因素 ,证明了满足一定条件的中断处理函数是可以分解的 ,提出了中断延时的最小化公式 ,给出了一个可以实现的软件模型 ,运用VToolsD和VC给出了实现方法 .实验表明 。

Based on the discussion of interrupt mechanism in the Win9x environment, the key elements impacting interrupt latency were analyzed. It was proved that interrupt process function could be decomposed. A formula to minimize interrupt latency was proposed. A software model was established to realize it by using VtoolsD and VC. The experiment results showed that the software model is of high performance in reducing interrupt latency.
