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...

有三个需要注意i的点: 1.这里是低电平有效,片选信号sel为低电平执行编码操作 2.因为需要有优先级,所以使用了问号表达式 3.有多个变量需要赋值,而begin-end一句一句赋值比较麻烦,所以这里采用{}连接操作符将3个变量整体赋值 二进制转十进制编码器(binary convert to decimal) 编码表和代码 余三编码器:余3实际上...
The code above is trying to convert an unsigned decimal of 12 into its binary representation, which is 1100, hold by the register B[3:0] and serve as output port as well. So could anybody help to give me some idea on how i solve this issue? Thanks in advance Regards, ...

In digital electronics, a decoder can take the form of a multiple-input, multiple-output logic circuit that converts coded inputs into coded outputs, where the input and output codes are different. e.g. n-to- 2n, binary-coded decimal decoders. Decoding is necessary in applications such as...

And i convert it directly. So if you wanna enter 45... you enter a 4 binary first, which then directly gets converted to 4 decimal, and then i take it times 10 in the program and so on... I'm only using two digit numbers so they can never be bigger than 99. Anyway, the ...
