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

• Octal <-->Binary: 1 Octal digit = 3 Binary digits Example: Convert 17532146312 8 to Base 16 Conversion Shortcuts • Octal <--> Hex: Convert to Binary, then to other base Binary Coded Decimal ( BCD ) 365 10 = 0011 0110 0101 ...
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 ...

Theuser_stringshall be of the form"plusarg_string format_string"where format strings are the same as$displaytasks. These format identifiers are used to convert the value provided via command line to the given format and store in a variable. ...
Optionally, adding an "s" to the end of the opcode identifier will tell the processor to set the condition codes as a result of the operation. For the following instructions, "offset" can be represented in many ways: A decimal number ranging from 0 to 511 (the offset field is 9 bits)...
