摘要
数字音频系统在CD机、手机、数字电视机等嵌入式数字系统中的应用越来越广泛。然而,目前国内对基于IIS音频总线协议的嵌入式音频系统的研究却较少。本文介绍了基于AT91RM9200和IIS总线的嵌入式音频设备的硬件体系结构及其Linux驱动程序的设计。它可以广泛应用在基于ARM内核的嵌入式系统中,具有很大的实用价值。
Many embedded audio systems have been applied into the CD,mobile phone and digital video and so on.But at present the embedded audio systems based on IIS Bus interface have not been studied much in China.The hardware system structure and design of Linux device driver of Embedded Audio device based on AT91RM9200 and IIS Bus interface have been introduced in the article. It can be widely used in the embedded systems based on the ARM core technique.
