摘　　要：相比于传统的ALSA(Advanced Linux Sound Architecture)架构音频驱动,针对嵌入式音频系统设计的ASoC架构音频驱动具有代码高度复用、动态电源管理等显著的优点。深入研究了嵌入式ASoC(ALSA System on Chip)音频驱动架构,实现了基于s3c2440和uda1341的嵌入式音频系统的ASoC架构音频驱动,并提出在ASoC架构音频驱动设计过程中为满足ASoC独立性原则可采用的设计思路和设计技巧。Comparing with traditional ALSA audio driver,the ASoC audio driver which is specially designed for embedded audio system has prominent advantages in many aspects including high code reuse ability and dynamic power management,etc.Based on the detailed research on embedded ASoC audio driver,the particular ASoC audio driver is well implemented for embedded audio system based on s3c2440 and uda1341,and the devising conception and some appropriate skills adoptable when designing the ASoC audio driver for satisfying ASoC independency principles are also presented and illustrated in this article.
