Objective:
The purpose of this lab is to introduce you to memory. Memory is the most important
device in any computer system. Since our programs and data must reside in memory, a good
understanding of how memory is connected to the microprocessor should come before learning to
write code. Unfortunately this requires covering a lot of material quickly. Below is a list of reading
materials that you need to review before you actually start the laboratory material. You are provided
pre-lab material to assist you in this process. You should start by locating and quickly reviewing the
reading materials listed so that you know where more information can be found on a given topic.
Then proceed to the pre-lab material and refer back to listed documents when questions arise.
Pre-Lab: Complete the following reading and attached pre-lab before coming to lab next week

Deliverables: Bubble Sort
(Due at the beginning of lab 2 Feb 5.)
Write a program that will sort a sequence of numbers located consecutively in memory. The
first number should be a count of the numbers to follow. Each number should be 32 bits in
size. This sequence of numbers should be pointed to by a variable in memory that contains
the address in memory where the numbers are located. Consider the code below.
