Simple, small assembly language program

Reprogramming the Multiply Instruction - working with shift instructions

Example attached.

Step 1

Write an x86 assembly language program which accepts two 32 bit numbers from the user and multiplies them without using multiplication instructions, using add and shift instructions. Store your 64 bit answer in the EDX, EAX register pair with the upper 32 bits in EDX. You do not need to output the answer.

Step 2

Test the program by multiplying a billion times a billion. The answer should be visible in the registers EDX = 0DE0B6B3 and EAX = A7640000.
