摘要
基于Windows 9x操作系统平台提出了利用虚拟设备驱动程序开发软件逻辑分析仪的方法 ,并开发了相应的软件。软件逻辑分析仪主要用于调试和逆向设计PC机扩展卡及其他外围设备 ,其基本功能是连续长时间捕获驱动软件对硬件设备发出的I/O端口操作指令。介绍了它的工作原理 。
A software logical analyzer developed by virtual device driver based on Windows 9x architectures was proposed and corresponding software was developed.The software logical analyzer is mainly used in debugging and reverse engineering of the expansion card and other peripheral device in PCs.Its basic function is to trap the I/O port accessing instructions continuously that hardware driver send to the device.The principle architecture and the functional extension was described.
