Using lc3 simulator.

use this lc3 simulator:

Write a program that calculates the result of z = xy
a. Store x and y in memory locations when writing your program (use .FILL)
b. The output of your result, z, should be left in register R3 at the end of your program
c. Assume (6 >= x >= 0) and (6 >= y >= 0)

Psuedo code:

.ORIG x3000
; **********************************
; REGISTER FUNCTIONALITY
; R0: multiplication (X) counter
; R1: exponentiation (Y) counter
; R2: scratch / math register
; R3: result
; R4 - R7: unused
; **********************************
; EXPLANATION
; To perform exponentiation, we can use repeat addition. Exponents are simply a form of repeated multiplication, which is repeated addition. We start with Z = X^0, which is 1. Then, add Z to itself X times to get X^1. Next, add Z to itself X times again which yields X^2. Repeat Y times until we get X^Y.
; Increment R3 by #1
; Load the value of Y (the exponent) into R1 (Y counter)
; If zero, branch to the label done (we have a zero power)
exp ; And R2 with zero (this clears the register)
; Load the value of X (the base) into R0 (X counter)
; Branch if nonzero to mul (we have a nonzero base, and want to skip the zero case)
; And R3 and zero (this handles the zero case)
; Branch if zero to done (skip the nonzero steps)
mul ; Add R3 and R2 and store in R2 (this will perform the addition step for multiplication)
; Increment R0 by #-1 and store in R0
; Branch only if positive back to mul (repeat addition)
; Copy the value in R2 to R3 (what command can we use to do that?)
; Increment R1 by #-1 and store in R1
; Branch if positive back to exp (repeat multiplication)
done ; halt execution
X .FILL x3 ; can be any non-negative 16 bit value
Y .FILL x5 ; can be any non-negative 16 bit value
.END
