输入一个序列,最新输入的数字为最低位,如果当前序列能被3整除,输出1,否则输出0。 例如:输入1010_1111,对应1,2,5,10,21,43,87,175,因此输出为:0000_1010. 编程思路 代码 `timescale1ns / 1psmodulesequence_divide_by_3(inputclk,inputrstn,inputdata,outputdivide_by_3 );parameterRemainder_0 =2'd0, ...

Verilog Examples - Clock Divide by 2 A clock Divider has a clock as an input and it divides the clock input by two. So for example if the frequency of the clock input is 50 MHz, the frequency of the output will be 25 MHz. In other words the time period of the outout clock will...

Divide by 3To implement a divide by 3, we need to count to 3 and so we will need two flip-flops to count states 2'b00, 2'b01, 2'b10. However since dividing factor is not equal to 2^n we need additional flip-flops to get a 50% duty-cycle. We can achieve this by shifting ...
③以一个简单的2分频器为例，它的功能是将输入时钟信号的频率减半。假设输入时钟信号 clk_in 的频率是10MHz，周期为100ns。对于2分频器而言，就是每经过2个 clk_in 的周期，输出信号 clk_out 的状态改变一次。④实现2分频器的verilog代码可以这样写：module divide_by_two(input wire clk_in,output reg clk_...
