Description
Assignment:
Write a MIPS assembly language program to calculate the area of each
trapezoid in a set of trapezoids. The sides should be read from wordsized aSides , cSides, and heights arrays. The result must be stored
into the word-sized tAreas array. Below is the formula to calculate the
area of a trapezoid:
tAreas[ n] = ( heights[ n] ×
( aSides[n] + cSides[ n])
2 )
After all the trapezoid areas have
been calculated, the program should
find the minimum, middle value,
maximum, sum, and average for the
trapezoid areas array.
The program must display the results
to the console window. The output
should look something like the
following (with the correct answers
displayed):

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:
# NSHE ID:
# Section:
# Description:
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.
Criteria Weight Summary
Assemble – Failure to assemble will result in a score
of 0.
Program Header 3% Must include header block in the
required format (see above).
General Comments 7% Must include an appropriate level of
program documentation.
Program Functionality
(and on-time)
90% Program must meet the functional
requirements as outlined in the
assignment. Must be submitted on time
for full score.
