Design of audio signal processing and display system based on SoC

In order to realize the real-time and efficiency of audio processing, as well as reducing the complexity of the waveform display processing, this paper designs a system of audio signal processing and display based on SoC. Using the Xilinx zynq-7000 development platform and taking advantage of efficient parallel processing capability of FPGA, it enables to do the real-time audio signal processing, and realize the volume adjustment, audio effect control and amplitude frequency conversion. In addition, due to the advantages in complexity control of ARM, the system can achieve the real-time dynamic output of the audio waveform with the method of combining software and hardware.
