| 摘 要： | 分析多周期同步测频原理及误差,在此基础上提出一种多周期同步测频的改进方法。该方法通过对标准频率计数值的修正,在不提高系统时钟频率和闸门时间的前提下,实现了测量精度的提高,并详细分析了其测量误差。最后,讨论了在FPGA中利用MC8051 IP核来实现真正意义的高性价比的SoPC频率测量问题。

| Abstract: | The modified method of multi-period synchronous frequency measuement is proposed by analysing its prineiple and error.Through revising the standard frequency counter value,the measurement precision is improved without increasing the frequency of system clock and time of gate.The measurement error are analysed in detail.The method to realize the low price-performance ratio of the SoPC frequency measurement with MC8051 IP core in the FPGA is discussed. |
