摘　　要：本文从工程应用角度出发,针对高速设备的传输特点,在嵌入式linux系统的驱动程序的一般结构基础上,进行设备驱动结构框架的改进,以满足高速数据流传输的需要。并以AT91RM9200与DSP的视频会议系统为例,说明该结构驱动程序的实现流程,并验证在嵌入式Linux系统高速数据传输应用的可行性与鲁棒性。From the aspect of engineering application, the paper gives the introduction of devices driver development which improves the gerneal linux driver structure for high-speed devices transmission so as to meet the need of high-speed data tramsmission . Furthermore, taking the driver on the video meeting system with chips of AT91RM9200 and DSP as the example, we introduce the process of the driver and prove such driver construction is feasible and rubust.
