Abstract

Audio signal transceiver module design is implemented based on FPGA in this paper, which processes and serially transmits the audio signal and switches the audio inputs in KVM (keyboard, video, and mouse) system. By reconfiguring and modify key parametric, the improved IIS bus and handshake signals are adopted in the design to widen application range and ensure the correctness of the serial transmission. Finally, the board test is done by FPGA, and the system possesses high performance and fine reliability.
