摘　　要：为了提高基于FPGA实现信号处理设备的集成度,增加接口设计的灵活性,便于协议的修改。介绍了一种基于Micro Blaze软核实现串口通信的设计方法,从MicroBlaze构成、开发流程、串口例化和中断设计方法等方面进行了分析,最终完成了串口通信设计及实现。测试结果表明,在115 200波特率条件下,FPGA串口长时间连续工作,不存在数据丢失情况,证明了采用此种设计方法具有较高的可靠性。In order to improve the integration of signal processing equipment based on FPGA, increase the flexibility of interfaces and implement easy protocol modification, this paper introduces a design method of implementing serial communication based on MicroBlaze IP core. The MicroBlaze composition, development flow, serial instantiation and interrupt design method are analyzed and the serial conmmnication is designed and inlplemented. The test results show that, at 115200 bauds per second, the FPGA serial port can continuoudy operate for a long time and no data are lost, which proves higher reliability of this design method.
