; This is a program to multiply two numbers. ; The program first stores a number into address x3100. ; The program then stores a second number into x3101. ; In a more complete program the two numbers would be read from the keyboard. ; In a more complete program the result would be written to the monitor.

2. The LC-3 does not have a multiply instruction. You will write a machine code (1s and 0s) program to allow for multiplication of two numbers. Your program will include the features listed below in steps a through d. It's best to complete each step and test before moving to the next step. Test to make sure that the program works in LC3. No credit if you write code in assembly. Your machine code file name must be Multiply bin a. Load register R3 with the number stored in memory location 3100. Load register R4 with the number stored in memory location 3101. The provided starter code already places data in these two memory locations. b. Write machine code to multiply the contents of R3 with the contents of R4. The result must be stored in R5. In other words, R5
