Abstract
Realize audio stream processing based on ZYNQ hardware platform. On the PS side of ZYNQ, the open source FFmpeg library is used to parse the audio compression data MP3 from the network audio data, and the audio compression data MP3 is audio decompressed to obtain the original audio data PCM, which is transmitted to the PL side of ZYNQ through DMA, based on Vivado The ila logic analyzer in the development environment captures the transmitted PCM data and displays the waveform. After testing and verification, the design function is stable, the software program starts efficiently and supports multiple protocols. The PL logic analyzer can capture the transmitted PCM data. In summary, this design can well realize the function of audio stream processing.
