Write an Assembly language program for the following expression using IAS computer Instruction set, Z$=($XY$).$ Consider that the data values are stored in memory location starting from $800$ onwards and the program is stored from memory location $400$ onwards. Assume that the value of X is $7$ and Y is $2.$ Represent the memory as follows:

MEMORY:

$400.$

$401.$

$402.$

PC

MAR

$800$

MBR

$801$

$803$

IR

IBR

D

Interpret the flow of execution in IAS Computer for the above Boolean expression using the following representation step by step. Also represent the register transfer code for each step.
