Assembly Code Multiplication

[DoomSlice]

Anyone know how to do an efficient Assembly Code multiplication of 2 15 bit numbers into a 32 bit register using the following operations:

nand rA rB dest
add rA rB dest
beq rA rB offset (branch to offset or label if rA = rB)
halt

I need to simulate bit shifting by using add and somehow use nand to figure out the product of the two by using some combination of nands.

This wouldn't happen to be a homework problem for junior level architecture, would it?

You wouldn't be trying to get someone to do your homework for you, would you?
