摘要
文章从硬件和软件两个方面介绍了DSP芯片ADSP-BF533与音频编解码器MC14LC5480接口电路的设计,详细阐述了通过同步串口(SPORT)和DMA进行音频编解码的实现方法。这种接口进行音频信号处理具有良好的通用性,不占用并行数据总线资源。
The design of audio interface between Audio Codec MC14LC5480 and DSP chip ADSP - BF533 is presented. How to set the registers of the SPORT and DMA in DSP according to the characteristic of TLV320AIC23B is described in detail. The design can be used in audio signal processing generally, which does not consume the parallel data bus.
