摘　　要：论述嵌入式Linux系统基于UDA1341芯片的音频驱动程序设计方法。该方法以UDA1341音频芯片及IIS(Inter-ICSound)总线为硬件架构,以OSS(Open Sound System)模型为软件基础,可以方便地扩充到其他应用平台。以实验证明了该方法的有效性。The paper discusses an audio driver programming design approach based on UDA1341 chip for embedded Linux system.This method makes use of UDA1341 audio chip and IIS bus as the hardware architecture and OSS model as the software foundation.It can be extended to other application platforms conveniently.The effectiveness of the approach is verified with experiment.
