CS 2734 Computer Organization II

• Prior to the laboratory, you should do the following:

  • Make a separate directory for laboratory 3 and put all of the code that you develop for this lab in that directory.

  • Write a MIPS program that allocates space for two integer arrays (A and B) of size 10. The program should do that following:
    • Read in the value of N (a number between 1 and 10).
    • Read in the first N values of the array A.
    • Compute the first N values of B as the accumulation of the array A (e.g. B[i] is A[0] + A[1] + ... + A[i]). Note: You must use a loop to implement this.
    • Output the first N values of the arrays A and B.

  • Be sure to thoroughly document your programs following the style of the programs discussed in class. (Insufficient documentation will bump an otherwise working program down to 8.)

• Implementation Notes:
  • Write a C version of this program first to make sure you understand it.
  • An example is:
    N = 8, A = [2, 4, 6, 8, 10, 12, 14, 16]
    B = [2, 6, 12, 20, 30, 42, 56, 72]

• For Checkoff:
  • Get a printout of your program using prtext. Give the program to the lab instructor before he starts your check-off procedure.
  • He will give you a card with the numbers you should enter for N and A.
  • Run your program for those values.
