Exercise #1: PC-Relative Addressing Mode

Assume you are given an array of four 16-bit numbers stored in memory with a starting address x3100. Using PC-relative addressing, write an LC-3 machine language program that will copy the same four 16-bit numbers in reverse order, starting at memory address x3110. For example, if the following are the four 16-bit values stored in x3100,

x3100	12
x3101	23
x3102	34
x3103	45

then the result of your program execution should write the following starting at memory address x3110:

x3110	45
x3111	34
x3112	23
x3113	12

Load your program starting at address x3050. You will need to demonstrate the correct execution of your program by using the LC-3 Simulator.
