摘　　要：随着DSP外围设备种类和数量的增长,外围设备的驱动编写和使用已经成为一项依赖于具体硬件和操作系统的必需任务。简述了基于DSP/BIOS的设备驱动模型,以TMS320DM642为开发平台,详细介绍了基于DSP/BIOS开发原始数据采集驱动程序的流程。完成了基于DSP/BIOS视频处理的基本程序框架设计,并将该驱动应用于Camera Link到SDI接口转换的项目中,实现了原始数据的采集、处理与实时显示。实验结果表明该驱动能很好地应用于需要采集原始数据的开发中。As the increasing of the kinds of peripheral equipment about DSP,the driver of peripheral equipment has to depend on real hardware and operating system.The device driver model based on DSP/BIOS was introduced.The diver development of RAW data capture based on BSP/BIOS was presented particularly.The design of elementary program structure about video processing which based on DSP/BIOS was finished,and it was used in the project of interface changing from Camera Link to SDI and actualized the collection and processing of RAW data and display in real-time.The results of the experiment show that the driver can be well used in the project of raw data capture.
