There are some processes that needs bigger area to implement it.
Correcting factor is also a need to correct what will be our output.
There are also something that we have learned in this subject by
exploring like the double dabble for having the converting output
of binary to BCD. Inputs and other operations must be fully
controlled in order to have a perfect simulation. The simulation is started on 2 inputs. Input A is implemented with the process of storing code by
using jk flip-flops and shift registering when it had implemented in 2-digits. An operation is also implemented when it has finished placing the first input. The operations that can be used are addition, subtraction, multiplication, division and every operation contains IC’s and other logic gates.
