摘要
文中利用TI公司提出的类/微驱动模型的驱动程序结构,以基于TI公司TMSDM6437 DSP的视频处理系统平台,在DSP/BIOS的基础上设计了视频输入输出设备底层驱动程序(给出了主要的程序),为高层程序开发人员提供方便的API接口函数来操作底层视频设备,提高了视频处理系统的开发效率。所阐述的视频设备驱动程序开发方法,对同类视频处理平台具有较好的借鉴性。
By using the driver structure of class/mini driver model and based on TMSDM6437 DSP video processing platform, the video input and output device driver （including a major procedure） is designed in DSP / BIOS. It provides a convenient API interface function for high level developer to operate the underlying video equipment, thus enhancing the efficiency of the video processing system. The proposed method for video device driver development （including the major procedure development） could be a good reference for the similar video processing platform development
