Description
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: 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.

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:
# Assignment: # 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.
