If someone wants to built an accumulator with logic gates such us the below:
I know how to make the full adder and the dff for the register but my problem is that in the first time input B will have an unknown value (right??). So how in the first time if we put for example A=0010 then we'll have sum_out= 0010 without a value in the B??
