Division of binary numbers logic circuit

+1
−0

If we want to divide two numbers I have problem implementing this logic.I am posting 1 images with 2 different steps to the solution.

In example a) the most significant digits of the divident >= divisor we subtract the divisor from those 2 digits.

hello

In b)the most significant digits of the divident<divisor so we move down the next digit of the divident(which happens to be the last) and we put a 0 in the quotient and do the subtraction.

I dont understand how to make a logic circuit which does that job:check if the divisors is greater and equal or less than the most left digits of the divident and depending on the results does a different function

You're thinking of a digital comparator, "a hardware electronic device that takes two numbers as input in binary form and determines whether one number is greater than, less than or equal to the other number."

I know that.Is there a way to use the comparator(s) as 'effeciently' as possible(no loops,storage of value ) and make a simple logic digital circuit?

If you know how to perform a desired operation with a loop and storage, you just need to unroll the loop. Instead of having multiple iterations of the loop you will have multiple instantiations of the hardware. You can also eliminate the registers for intermediate values if you can guarantee that the inputs will remain stable long enough for the final result to be calculates. Most people would say this is the opposite of "as efficiently as possible", but it's up to you.

It is not clear to me what you do know and what you don't know. You should edit your post to reflect these. Do you know how to make a sequential circuit? For example, do you know what a state diagram is and what a finite state machine is?
