Gray code is a binary code where each successive value differs from the previous value by only one bit. Implementation #1 module bin2gray #(parameter N=4) ( input [N-1:0] bin, output [N-1:0] gray); genvar i; generate for(i = 0; i < N-1; i = i + 1) begin assign gray[...

Conventional binary counters use complex or wide fan-in logic to generate high end carry signals. A much simpler structure sacrifices the binary count sequence, but achieves very high speed with very simple logic, easily packing two bits into every CLB. Such Linear Feedback Shift-Register (LFSR)...

格雷码(Gray Code)转换为二进制码的基本思想是:保留格雷码的最高位作为二进制码的最高位,从次高位开始,每一位都是其左边一位与格雷码对应位异或的结果。 以下是一个简单的Verilog模块示例,用于将格雷码转换为二进制码: verilog `timescale 1ns/1ps module gray_to_binary #( parameter N = 4 // 定义格雷码和...
A second Gray code counter style, the one described below, uses two sets of registers, one a binary counter and a second to capture a binary-to-Gray converted value. The intent of this Gray code counter style #2 is to utilize the binary carry structure, simplify the Gray-to-binary conve...

assign gray_value=binary_value^(binary_value>>1); 格雷码转换为二进制码的过程 该过程也称为格雷码的解码,方法是从格雷码左边第二位(次高位)起,将每一位与其左边一位解码后的值异或,作为该位解码后的值,而最左边一位(最高位)的解码结果就是它本身。对应公式如下: ...
