Kris,

definitely yo can do the whole process in one go.
For that either you have to write a simple program which tells you the bit
combinations or
since in your case, data is just 8 bits, so you can manually derive the
equation

But I guess, the synthesis tool will be doing the same thing for you, if you
just write everything in loop, can't guarantee but it should do so.....
