| Abstract: | Designing a linux- based embedded audio data acquisition system whose main function is to collect audio data for the speaker power experiment. This digital audio hardware system with Samsung＇s S3C2410 as the control core, through IIS audio bus and CIRRUS LOGIC＇s CS5396 encoding chip constitutes embedded audio system and achieves the acquisition of audio data. This paper introduces IIS bus of linux, the driver of IIS, the interface design of CS5396 A/D conversion chip,and illustrates the working principle and related configuration of each interfaces. The audio data collection scheme can acquire data for different audio data precision and achieve the 24 audio data collection requirements in the highest according to different sampling requirements. |
