The program is A Subroutine is a set of instructions designed to perform a specific task that can be reused multiple times within a program. 16-bit division is the division of one 16-bit value by another 16-bit value, returning a 16-bit quotient and a 16-bit remainder. Write a subroutine that will divide a 32-bit unsigned number into another 32-bit unsigned number. I try to divide 32 bit number in 16 bit number. , there are no division instructions), so subroutines must be written using This is also why multiplication takes longer than bit shifts or adding - it's O (n^2) rather than O (n) in the number of bits. Write an ALP to find the product of two unsigned binary numbers stored at location ‘X’ and ‘X+1’ by shift left and add method and display the product in address field. I understand that by division of 4 which means i have to shift the bit by 2.
