Gray code counters (having one bit change per counter transition) are often used in FIFO design and digital communication. Here I will show two styles gray code counter. Style #1 First style gray code counter uses a single set of flip-flops as the Gray code register with accompanying Gray-t...

计数器 ●同步计数器:所有寄存器共享一个时钟 ●异步计数器(行波计数器):不断地分频 下图就是一个行波计数器的实例: example:5-bit up-by-one down-by-two counter 小结:上述代码实现的就是最简单的同步计数器。 Example: 用LFSR(线性反馈移位寄存器)... ...

题目:Create a circuit that has two 2-bit inputsA[1:0]andB[1:0], and produces an outputz. The value ofzshould be 1 ifA = B, otherwisezshould be 0. 大白话:给定两个两位输入A,B,一个输出z。如果A=B,则z=1;如果A≠B,z=0. ...

So if you know the inputs are mutually exclusive, then you can code the logic in parallel if. 1 module parallel_if(); 2 3 reg [3:0] counter; 4 wire clk,reset,enable, up_en, down_en; 5 6 always @ (posedge clk) 7 // If reset is asserted 8 if (reset == 1'b0) begin ...
