摘要
论述了Linux操作系统中声卡驱动程序的设计方法,主要介绍了基于OSS的声卡驱动设计原理以及Linux操作系统中声卡驱动程序的接口函数。针对具体硬件平台编写了相应的驱动程序,并介绍了在Linux操作系统中使用声卡设备的几种常见方法。实现了SEP4020处理器在Linux平台的声卡驱动。
In this paper, a method is provided to design a Linux sound driver based on OSS. The OSS theory in Linux has been introduced. To accomplish the sound driver, a few structures and functions should be filled by the designer. This paper also provides some ways to use the sound card in Linux. The SEP4020 microprocessor has been used in Linux sound driver in this paper.
