摘　　要：本文介绍了一种采用ARM处理器S3C44B0的MIDI音乐发生器软硬件设计及实现方案,S3C44B0通过与上位机通信获取人声基频数据并快速地进行识别处理,最后将其转换为MIDI音源芯片所能识别的MIDI消息,从而使MIDI音源发出与人声基频相对应的不同音色的电子乐音。This paper introduces the hardware and software design and implementation program of MIDI music generator based on ARM processor S3CA4B0. Through communication with the PC, S3CA4B0 acquires the frequency data of human voice, identifies and deals with them quickly. Finally, the data will be converted to MIDI messages which can be identified by the MIDI sound source chips, causes the MIDI sound source to send out the electronic musical note. This kind of notes has the same frequency but different tonal with the sounds of human voice base frequency.
