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...

Dear all, I have some problem with the implementation of unsigned decimal to binary conversion. I need this conversion for my 32-bits fast adder

No style guide is perfect. There are times when the best path to a working design, or for working around a tool issue, is to simply cut the Gordian Knot and create code that is at variance with this style guide. It is always okay to deviate from the style guide by necessity, as lon...

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 ...
