This homework is due on Monday, Feb. 21st, at 9:00 a.m. You should make sure that you have gone through all the steps of Lab #3 as preparation for this homework.



You may find the information in the following two documents very useful for working on this homework:

Problem #1

  • Use the Processor/Memory simulator and write a program that starts with 4 numbers stored in memory Locations 14, 15, 16, 17, and that stores the sum of all 4 in memory Location 18.
  • When you program works correctly, copy it to a text file of your choice. Save the file for right now.
  • Use labels in your program for instructions and for data (as described in xComputer Lab 2).
  • Try to be efficient and attempt to use as few instructions as possible.

Problem #2

  • Write another program that computes the sum of the integers 1, 2, 3, 4, 5, 6, 7, 8, 9 and 10, and stores the sum in Memory Location 20 (or other convenient location). Your program should stop when it has finished adding the number 10 to Memory Location 20.
  • Make your program store the ten numbers 1, 2, 3, ... 10 in 10 memory locations, and add them up to compute the sum
  • Your program should stop automatically when it is done.


  • As with Problem 1, copy your solution program at the end of the file you created for Problem 1.

Problem #3

  • Same as Problem #2, but without storing the ten numbers in memory. The program should generate all the numbers required in the accumulator, and use only 1 memory location to store data.
  • As with Problem #2, copy your solution to a file to the end of the same file as Problem 1 and Problem 2.

Submission

  • Email the file containing the solution to all 3 problems as an email message (no attachment, please!), and address it o 103b@cs.smith.edu. Make sure your name is at the top of the text of your message.
