摘要
将可编程计数器和高精度延时器MC100EP196相结合,实现了延时器的大范围、高精度调节。在EP1C6Q240内将可编程计数器和MC100EP196控制电路制作成SOPC组件,通过Avalon总线与NIOSII连接,实现了可编程延时器的扫描控制。通过该设计驱动的采样电路测试结果,说明了电路的可行性。
Combining programmable counter and MC100EP196, the programmable delayer is realized in broad time delay and high precision. Constructing programmable counter and control circuit of MC100EP196 in SOPC Builder component, which is controlled by NIOS Ⅱ through Avalon Bus, the delay scan is implemented. The validity of the design is demonstrated by the equivalent sample results.
