BCD Subtractor (WIP)

[seankingman]

Hi,

I've posted this topic to inform you that I have now reached a milestone in the design and construction of the BCD Subtractor. I have now just finished designing my own 9's compliment subtractor which will form the basis of the BCD Subtractor. At the moment it just looks and functions like an overly-complicated, oversized and slow subtractor but it will soon be able to output negatives.

Here's some pics:





P.S: I'd also like to thank Newo for the adder design.

Fancyness! Are you making a calculator that works all in bcd? That would be amazing

Thanks Newo! I will eventually when I get it bug-free as I've got a BCD adder design sitting on my plot too.

Learning BCD would be nice...
