摘　　要：给出了一种测周的数字频率计的SOPC实现方法.该方法通过配置嵌入式软核MicroBlaze微处理器和封装AXI测频和测占空比IP核,将数据传输到软核处理器,完成系统的功能.数字频率计的参数测量由FPGA逻辑进行实现.计算、控制以及显示由MicroBlaze实现,两者完成对频率和占空比的测量.本系统在Digilent公司推出的Basys3板卡上进行了验证.通过测试,结果表明,本系统测量精确,稳定性好,方案简洁,成本较低.达到了预期的结果,验证了本方案的可行性.An SOPC method for measuring the digital frequency meter was designed. This method configured the embedded soft- core MicroBlaze microprocessor and encapsulated the AXI frequency measurement and the measured duty-cycle IP core to trans- mit the data to the soft-core processor to complete the system function. MicroBlaze calculated the data and controlled the sys- tem. The system was validated at Digilent＇s Basys3 board. The results showed that the system was accurate, stable, simple pro- gram and low cost through the test. The design fulfilled the expected results and verified the feasibility of the program.
