MIPS Assignment #2

Purpose:    Become familiar with RISC Architecture concepts, the MIPS Architecture, and SPIM
(the MIPS simulator).
Points:    50


Assignment:

Write a MIPS assembly language program to calculate the total surface area of each three dimensional trapezoid in a series of trapezoids.

The total surface area of a three dimensional trapezoid is computed as follows:






aSide

cSide
dSide
height


length
bSide


surfaceAreas[ n] = aSides [n] × (lengths[ n] × heights [ n] ) + bSides[ n] × (lengths [n] × heights[ n] ) + lengths[ n] × cSides[ n] + lengths[ n] × dSides [n]

Once the values are computed, the program should find the minimum, maximum, middle value, and average for the computed total surface areas.


The program should display the results to the console window. The output should look like the following ,with the correct answers displayed. The numbers should be displayed with two (2) spaces before each number, and 5 numbers displayed per line. There should be one (1) blank line before the numbers and one (1) after the numbers. The instructions to display the headers and answers are included in the template.

Of course, you will need to calculate the correct answers first.

Surface Areas Minimum = ?

Surface Areas Middle    = ?
Surface Areas Maximum = ?

Surface Areas Sum    = ?
Surface Areas Average = ?
Submission:

    • All source files must assemble and execute with QtSpim/SPIM MIPS simulator.

    • Submit source file
        ◦ Submit a copy of the program source file via the on-line submission

    • Once you submit, the system will score the project and provide feedback.
        ◦ If you do not get full score, you can (and should) correct and resubmit.
        ◦ You can re-submit an unlimited number of times before the due date/time.

    • Late submissions will be accepted for a period of 24 hours after the due date/time for any given lab. Late submissions will be subject to a ~2% reduction in points per an hour late. If you submit 1 minute - 1 hour late -2%, 1-2 hours late -4%, … , 23-24 hours late -50%. This means after 24 hours late submissions will receive an automatic 0.


Program Header Block

All source files must include your name, section number, assignment, NSHE number, and program description. The required format is as follows:

    • Name: <your name>
    • NSHE ID: <your id>
    • Section: <section>
    • Assignment: <assignment number>
    • Description: <short description of program goes here>

Failure to include your name in this format will result in a reduction of points.


Scoring Rubric

Scoring will include functionality, code quality, and documentation. Below is a summary of the scoring rubric for this assignment.
