| Abstract: | 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. |
