摘　　要：设备驱动程序在Linux内核中占有重要的地位，它是负责实际硬件设备的特定操作的映射。为了实现多通道同步数字记录仪在Linux下对多通道话音数据的实时采集，给出了多通道话音采集压缩卡的驱动程序的设计，描述了驱动程序的初始化过程，提高了系统的可靠性。最后分析了驱动程序的稳定性与实时性。Device driver in the Linux kernel plays an important role,which is responsible for the mapped of the actual hardware-specific operations.To achieve the real-time multi-channel voice data collection in Linux of simultaneous multi-channel digital recorder, we proposed multi-channel voice capture and compression card driver design,described the initialization of the device driver, Finally we analyzed the stability and real-time of the driver in Linux.
