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[...
【Verilog_H..1二进制码转换成格雷码比较简单,一步到位 gray=(bin>>1)^bin;2.格雷码转换成二进制码稍显复杂,需要递推说明:将格雷码最高位赋值给二进制码最高位,即bin[N]=gra
Binary(二进制编码)、gray-code(格雷码)编码使用最少的触发器,较多的组合逻辑,而one-hot(独热码)编码反之。one-hot 编码的最大优势在于状态比较时仅仅需要比较一个bit,一定程度上从而简化了比较逻辑,减少了毛刺产生的概率。另一方面,对于小型设计使用gray-code和binary编码更有效,而大型状态机使用one-hot更高效。 ...

状态编码种类: 在数字逻辑系统设计中,一般常见的数字编码方式有: 二进制码(Binary 码) 格雷码(Gray 码) 独热码(One-hot 码) 独冷码(One-cold 码) 二-十进制码(BCD 码)等。 7.5 状态编码 定义方式: Verilog HDL 一般采用参数进行状态编码,也可以采用`define 宏定义的方式进行编码——但一般不推荐此方式。

Since we need to represent the state machine in a digital circuit, we need to represent each state in one of the following ways: Binary encoding : each state is represented in binary code (i.e. 000, 001, 010...) Gray encoding : each state is represented in gray code (i.e. 000, ...
