摘　　要：本文基于FPGA设计了一组串口电路系统,利用该系统可实现微控制器的串行数据通信接口的扩展需求。为验证该串口电路系统的功能,还基于单片机STC12C5A60S2设计了手机遥控MP3音频播放系统。经测试,单片机利用FPGA串口电路可控制MP3音乐播放,证明FPGA串口电路实现控制指令传输功能。该工作为单片机的多串口扩展提供依据,促进单片机系统方案的多样性。This paper designs a Series-port circuit system based on FPGA,which can realize the expansion requirement of serial data communication interface of MCU.In order to verify the function of the serial circuit system,a remote MP3 audio playback system based on STC12C5A60S2 is designed.After testing,the MCU can control MP3 music playing by using the serial port circuit of the FPGA,which proves that the serial port circuit of the FPGA can realize the control instruction transmission function.This work provides a basis for the expansion of multi-serial ports of single-chip microprocessors and promotes the diversity of single-chip system schemes.
