【摘要】基于Altera公司FPGA芯片EP2C8Q208,嵌入MC8051 IP Core,用C语言对MC8051 IP Core进行编程,以其作为控制核心,实现系统控制。在FPGA芯片中,利用Verilog HDL语言进行编程,设计了以MC8051 IP Core为核心的控制模块、计数模块、锁存模块和LCD显示模块等几部分,实现了频率的自动测量,测量范围为0.1Hz~50MHz,测量误差0.01%。并实现测频率、周期、占空比等功能。%This design is based on Altera's cyclone II series FPGA,and used Verilog HDL hardware description language as a tool for the design of digital frequency meter.with its core as a system control,the MC8051 IP Core embedded in FPGA chip,using C language programm on the MC8051 IP Core;in the FPGA chip using Verilog HDL programming language designed the MC8051 IP Core,counting modules,latching module and LCD display modules and other parts and realized the automatic measurement of frequency,namely: adaptive regulation,measurement range 0.1 Hz to 50 MHz,measurement error is small.Enables measurement frequency,period,duty cycle and other functions.
