Custom bit widths

[blakaxe]

How do i create basic datatypes with custom bit widths?

Example: I need a 20 bit signed integer.

I am modeling hardware that can have custom bit widths. How do I do it in C++?

You will need to write a class that wraps an int and ensures that the value never exceeds the range of a 20-bit signed integer.

You can also use bitfields/bitsets and manually convert the bits into whatever type you want them to be.

a bit field

struct bit_field{
    unsigned field : 20; // 20 bit 
}
