Abstract：To solve the problems of poor scalabilityand weak anti-interference capability in traditional wireless transmission systems，this paper proposes a design of a wireless audio transmision device based on SoC FPGA.The design takesFPGA as thecore platform，adopts ahardware-softwarecoordination architecture，andintegrates modulessuchas the RISC-Vmicroprocso，digitalFMbaseband modulator，DAC，phase-lockedloopandmixer toealizethefunctionsofdigital FMmodulation，digital-tonalogonvesion，up-onversio，andwirelesstransmissonfordisigals.C-languagepgas are compiled inthe CDKenvironment，and theRISC-Vmicroprocessordynamicallconfigures parameters includingfrequency controlwordsand frequencydeviationcoeffcients toachieveaccurateFMmodulation.Experimentalresultsshowthatedesign has the advantagesofaclearstructure，strongrepeatabilityndightransmissionefciencywhichverifies theapplicationvalue of SoC FPGA in the field of wireless communication.
