- Enter the operands in 2's complement form. The dividend
is 15 bits long and will be loaded into the register pair
A(0:7)Q(0:7). This register pair is also used to store the partial
remainders. The divisor is 8 bits long and is placed into register
M.
- The flipflops MS and AS store the signs of divisor
and dividend. DZ will be set if the divisor is equal to zero.
- In each step A.Q is shifted to the left. The bit at the
rightmost end of the register Q is used to store the quotient bits as
they are generated.
- When the division process terminates, Q contains the quotient while A
contains the remainder to be shifted n-1 places to the right.
