| 摘 要： | 由于单片机受本身时钟频率和若干指令运算的限制,若单独使用它来开发测频系统,测频速度较慢,无法满足跳频检测设备中高速测频的需求.为满足跳频通信中测频应变速度快、灵敏度高的要求,本文将介绍一种以FPGA为测频核心处理芯片、单片机(C8051F020)为数据处理器的高速测频系统的设计方法,并详细地介绍了系统的组成, FPGA的设计、功能仿真等.实验结果表明,该方案完全符合设计要求.

| Abstract: | Because of the self limitation of clock frequency and instruction operation in MCU, speed in the frequency measuring system developed by MCU alone is relatively slow, which is unable to meet the strict requirements of high-speed frequency testing in frequency hopping communication. In order to meet the request of the rapid response and high sensitivity in frequency testing, this paper introduce a method of the high-speed frequency measurement system which takes the FPGA as the core process chip and the MCU(C8051F020) as the data processor. Composition of the system is discussed in detail, and simulation for FPGA is also given, which show that the scheme for the system matches to the requests completely. |
