CyclonePLL
- Cyclone™ FPGA具有锁相环(PLL)和全局时钟网络,提供完整的时钟管理方案。Cyclone PLL具有时钟倍频和分频、相位偏移、可编程占空比和外部时钟输出,进行系统级的时钟管理和偏移控制。Altera® Quartus® II软件无需任何外部器件,就可以启用Cyclone PLL和相关功能。本文将介绍如何设计和使用Cyclone PLL功能。 PLL常用于同步内部器件时钟和外部时钟,使内部工作的时钟频率比外部时钟更高,时钟延迟和时钟偏移最小,减小或调整时钟

design_4
- 利用48M时钟信号定时得到事先设置好的延时,通过延时信号接到蜂鸣器发出提示声音。主持人,抢中,抢答时间到,答题时间到,四个信号分别触发计数延时,最后把得到的三个报警信号相与(因为系统设置为低电平有效),作为最后的报警信号。 每个触发延时计时,在触发信号无效(‘1’)时,将计数值归零,触发信号有效时(‘0’),开始记时钟个数,记到一定(根据需要事先设置好)个数,就得到延时时间(延时时间=时钟个数*时钟周期),时间延时报警信号无效,得到一定时间的报警信号。 -48M clock signal t
