vhdl integer division

you can do repetetive subtraction for it. Or
you can use Newton-Raphson method for it

if you are dividing the number by 2^n means(2,4,8,16,32.......)
then you can shift left directly the number by n bits.

Another possible approach is to tabulate 1/T in a Block ROM, and then multiply (K*N) * (1/T)

Hi everybody,

i'am trying to do just this:
varU2int <= U2 /2; with (varU2int : integer range 0 to 1023 :=0

and my problem is: i have some bit like varU2int(10) on 'U' and not (0 or 1)
how i can avoid this?

U2 / 2 is the same as doing 1 right shift to U2
