| Abstract: | According to the characteristics of TI' s stereo audio codec chip TLV320AIC23 and combining the applications of digital signal processing and embedded system, a hardware interface circuit consisting of TLV320AIC23, TI' s DSP chip TMS320VC5402 and Samsung' s ARM chip S3C4510B is designed. The interface control programming is accomplished through ARM' s I~2C interface. DSP exchanges data with AIC23 through its multichannel buffer serial port and accomplishes the processing of audio signal. This system is practicable in sound codec processing, voice recognition and sound controlling fields. |
