Homework 1

Short Description:

This program is intended to help you become familiar with MIPS assembly programming.

This assignment is worth 20 points.

Goals

When you finish this homework, you should:

Be able to create, MIPS programs.
Be able to execute MIPS programs.
Be able to document MIPS programs.
Be able to run a MIPS simulator.
Have your programming environment established for the semester.
Referenced extra material on the CD included in the book.

Formal Description

Read appendix B.9 SPIM on page B-40 to B-45
Read the appropriate spim tutorial on the CD.
- Getting Started with xspim, resources/xspim.pdf
- Getting Started with PCSpim, resources/PCSpim.pdf
- Getting Started with spim, resources/spim.pdf
Locate at least three other sets of reference material for spim on the web.
Using an editor, enter the following program.
Correct any errors, debug and run your program.
Add appropriate comments, including your name.

Add statements which will produce:

Program 1, Computer Architecture, Fall 2009
This program is from page B-7 of Patterson and Hennessy
Program run by _Your Name Here_
-----------------------------------

Replace _Your Name Here_ with your name.

Add code to produce
```
   i = ###,  Total = ####
   
```
at the bottom of each iteration of the loop. Where ### is replace with the current value of the LCV and #### is replaced with the current total.

Output

Your output should look something like:

Program 1, Computer Architecture, Fall 2009
This program is from page B-7 of Patterson and Hennessy
Program run by Dan Bennett 
-----------------------------------
i = 1, 	 Total = 1
i = 2, 	 Total = 5
i = 3, 	 Total = 14
...
i = 100, Total = 338350
-----------------------------------
The sum from 0 .. 100 is 338350

Discussion

You may use any MIPS simulator you wish, but I will grade your homework using xspim 7-4. It must run under this simulator.

Required Files

The body of your email must contain the following statement.

"I do solemnly swear (or affirm) that I have read the assigned reading. I also swear (or affirm) that I have made the additions to the code myself, and I understand what these additions do."

You should also include the links to reference material you found.

You should attach your modified program.

I intend for you to type the code. I want you to look at the code as you enter it. It would be really useful for you to look the instructions up on the green MIPS Reference Data sheet. Notice where the nemonics are classified. Further notice the use of registers.
