摘要
本文采用基于计数空间完全划分和周期插入控制计数过程方法设计了非幂方分频器 ,采用这种全新思路设计的非幂方分频器分频范围很宽 ,分频输出对后续分频支持好 ,非常适用于通讯接口中的波特率时钟设计 .此外 ,这种设计思路对系统定时电路和节拍控制电路设计也有一定的借鉴意义 .
The core of the traditional arbitrary frequency divider is periodically resetting.This paper proposes a new concept for frequency divider,in which control element is periodically inserted into a counter to avoid reset.The mathematical work of the new concept is given in the paper.An algorithm based on the new concept is introduced also.And,a design practice based on the algorithm shows a visible improvement in terms of both performance and recourse cost,compared with the traditional design methodology.
