Abstract: To address the insufficient hardware implementation in digital signal processing teaching, a signal processing experimental platform based on Gowin FPGA was developed. The platform utilizes the Gowin ACG525 development board, integrating audio acquisition and playback modules, signal processing modules, and parameter control modules, supporting the development and implementation of various signal processing algorithms. Through modular design, the platform achieves audio signal acquisition, processing, and playback, and provides commonly used IP cores such as FIR, IIR and FFT. The platform enables students to flexibly invoke and configure resources, supporting the offering of diverse experimental projects of different types and levels, such as voice signal sampling and playback, filter design, audio signal resampling, and echo and reverb effects generation. This helps students gradually grasp the core theories and hardware implementation methods of signal processing, thereby improving their system debugging capabilities and engineering practice skills.
