If the binary value in any of the BCD columns is 5 or greater, add 3 to that value in that BCD column. Go to 1. Example 1: Convert hex:0xE to BCD Example 2: Convert hex:0xFF to BCD Truth table for Add-3 Module Here is a Verilog module for this truth table. module add3(in...
因为用verilog写程序时虽然形式上可以写为比如256,但是实际存储对应的还是0100H,且一个数码管只能显示一个十进制数。因此这个问题相当于二进制如何转换为一个BCD(Binary Code Decimal)码数。 本文只考虑最常见的8421码的转换,而且是压缩BCD码。 一、算法原理 根据二进制与十进制转换的定义可知,将二进制数按位加权求...

You are provided with a BCD (binary-coded decimal) one-digit adder named bcd_fadd that adds two BCD digits and carry-in, and produces a sum and carry-out. module bcd_fadd { input [3:0] a, input [3:0] b, input cin, output cout, ...
im trying to make a BCD converter with 5 input but there is something wrong with what I have here. --- Quote End --- Actually there is not 'something' wrong: that code is completely wrong. Google "binary bcd converter verilog" and you'll get tons of code samples....
In this work we propose optimized Binary adders and BCD adders. The adders designed in this work are optimized for Quantum cost, Delay and Area. A modified BCD adder is also proposed which removes redundancy in the circuit and acts as most efficient BCD adder. Here we explore the use of ...
答案: module binary_subtractor( input [3:0] A, // 被减数,4位宽度 input [3:0] B, // 减数,4位宽度 output reg [3:0] result // 结果,4位宽度 ); assign result A - B; // 用连续赋值语句实现减法 endmodule 5.4实现四舍五入功能电路,当输入的1位8421BCD码大于4 时输出为1,否则为 0试...
