CPE 315
Winter 2008
Laboratory Project #2
Due by 3:10 pm, Tuesday Feb. 5

1. This is an individual assignment.
2. All submission and plagarism rules are in effect.
3. Don't use any MIPS pseudoinstructions, except la, in this lab.
   
4. You can assume there are no overflows generated by your program.
   

• To learn how to write MIPS assembly code.
• To appreciate the la pseudo instruction.

Description:

1. Write a MIPS program
   Write a program that inputs a set of integers (both positive and negative), terminated by a 0.
   The program determines the smallest integer, the total number of integers and the number of even/odd integers.
   The results must be displayed on the XSPIM console window.
   

   Constraints and Hints
   

   1. la
      You may use the la pseudo-instruction but no other pseudo instructions.

   2. No priming read
      Do all of the inputs with one syscall, inside a single loop. No priming read permitted.
      

   3. Initialize smallest
      Initialize the register that holds your smallest value to maxint.
      

2. Test Cases
   If you've forgotten how to generate proper test cases, talk to me during lab time.
   Proper test cases are a major part of this lab grade.
   

3. Prove the program works
   Be sure you can run the program with this command line:
   

   xspim   -nopseudo -file lab2.asm

   
   Do screen prints of (at least 3 good) test cases that prove your program works.
   If you prefer, you can demo your program during lab on Feb. 5; include your test cases in the formal lab report.
