Gowin FPGA-Based Signal Processing Experimental Platform Design

To address the insufficient hardware implementation in digital signal processing education, a signal processing experimental platform based on Gowin FPGA was developed. The system utilizes the Gowin ACG525 development board, integrating audio acquisition, signal processing, and output modules to support the development and verification of various signal processing algorithms. Through modular design, the system achieves audio signal acquisition, processing, and playback, and provides commonly used IP cores such as FIR and IIR. The platform enables flexible configuration and invocation by students, supporting diverse experiments across various levels, such as voice signal sampling and playback, filter design, audio signal resampling, as well as echo and reverb effects generation. The results demonstrate that the platform effectively enhances students' engineering practical abilities, providing strong support for digital signal processing course teachings.
