2、8-bit up counter with load *** module up_counter_load ( output reg [7:0] out , // Output of the counter input wire [7:0] data , // Parallel load for the counter input wire load , // Parallel load enable input wire enable , // Enable counting input wire clk , // clock ...
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...

大白话:输入一个3位向量,输出这个向量中1的个数 思路:和之前一道题类似,就是把向量的每一位都加起来。 答案: moduletop_module(input[2:0]in,output[1:0]out);always @(*)begin out=0;for(int counter=0;counter<3;counter++)out=out+in[counter...
