;x-y NOT R3, R1 ADD R3, R3, #1 ADD R4, R0, R4 STI R4 sub

; absolute value x

;absolute value y

ARITHMETIC FUNCTIONS 2.1 Problem Statement The numbers X and Y are found at locations x3120 and x3121, respectively. Write a program in LC-3 assembly language that does the following: . Compute the difference X -Y and place it at location x3122. . Place the absolute values l and P1 at locations x3123 and x3124, respectively . Determine which ofand P1 is larger. Place l at location x3125 if XI is, a 2 ifIYI is, or a 0 if they are equal. 2.1.1 Inputs The integers X and Y are in locations x3120 and x3121, respectively: x3120X x3121Y 2.1.2 Outputs The outputs at their corresponding locations are as follows x31 x3123 x3124Y x3125Z where Z is defined as Revision: I.II, Jamuary 26, 2007 2-1
