PCI总线MPEG-Ⅱ编码器驱动程序的开发

The Development of Device Driver Program of the MPEG-II Encoder Based on PCI Bus

描述了在WIN98操作系统下编码器驱动程序的开发原理 ,并提供了软件的设计方案 .阐述了实现该方案所创建的虚拟设备驱动程序 ,并简要介绍了主控程序 .实验结果表明 ,此软件能够支持编码器正常工作 .

The MPEG Ⅱ encoder Dvxpert Ⅱ integrated in a Plug and Play PCI card is introduced. The principle of development of device driver is discussed under WIN98. The software design of the device driver program and the control program is also elaborated. The experimental results show that the software runs well and the encoder works as expected.
