FPGA-based SCM and the frequency of monitoring system

论文介绍FPGA和单片机SPCE061A共同实现频率检测系统的设计。利用FPGA的高速、精确特点产生任意波形并能对波形进行步进调节和测量波形的频率、周期、脉宽及占空比等,利用单片机实现语音播报和液晶的实时显示。该系统具有频率测量范围宽、产生的波形频率分辨率高及精度大等特点,设计具有较高的实用性和可靠性。

In this paper, FPGA and single-chip SPCE061A together achieve a frequency detection system Any form of wave were made by FPGA with its high-speed and precise characteristics, they can measure the frequency, period, pulse width of the wave. voice broadcast and LCD screen througth the SPCEO61A achieve frequency broadcast and display. The systemhas a wide frequency range, the resulting wave of high resolution and accuracy and so on. This designed possess high practicality and reliability.
