This is the code that needs to be updated:

.ORIG x3000
LD R0, NUM
LD R1, DEN
JSR GCD
ADD R4, R1, #0
ADD R1, R2, #0
JSR DIVIDE
ST R2, NUM
ADD R0, R4, #0
JSR DIVIDE
ST R2, DEN
HALT
; you can try other values for NUM and DEN by replacing these values in the simulator
NUM .FILL #10
DEN .FILL #3

; Divide R0 by R1, putting quotient in R2 and remainder in R3
DIVIDE

; Euclid's algorithm for GCD of R0 and R1, result in R2
GCD

.END

Background: Fractions are simplified by dividing the numerator and denominator by their greatest
common denominator (GCD). In this assignment you will write two subroutines, which are used by
the main program
to simplify a fraction stored at the end of the program. The first
subroutine divides two integers using repeated subtractions, something you did for assignment 2 and
will write now as an assembly language subroutine. The second subroutine implement's Euclid's GCD
algorithm, and makes use of your divide subroutine.
Here is pseudocode for Euclid's algorithm given the numerator x and the denominator y:
while y > 0
end
r = remainder of x/y
X = y
y
r
=
#remainder is in x
Your job: Write two subroutines to complete the program given in fraction.asm:
1. DIVIDE: Divide R0 by R1, putting quotient in R2 and remainder in R3
2. GCD: Euclid's algorithm for GCD of R0 and R1, with result put in R2
