CS 218 – Assignment #5

Purpose: Learn to use arithmetic instructions, control instructions, compare instructions, and

conditional jump instructions.

Points: 80

Assignment:

Write a simple assembly language program to calculate some geometric

information for each kite (see diagram to the right) in a series of kites. c q Specifically, the program will find the area and perimeter for each of the kite in a

set of rectangular kites. Once the values are computed, the program should find the minimum, maximum, middle value, sum, and average for the areas and perimeters.

kiteAreas [ n] =

pSides [n] ∗ qSides[ n]


2

kitePerims [ n] = 2 × aSides [n] × cSides[ n]

p

a

Since the list is not sorted, we will estimate the median value. Since the list length is odd, the estimated median will be computed by summing the first, last, and middle values and then dividing by 3.

Do not change the sizes/types of the provided data sets. All data is unsigned. As such, the DIV/MUL would be used (not IDIV/IMUL). Also, CDW/CWD/CDQ would not be used (as they are for signed data). The JA/JB/JAE/JBE must be used (as they are for unsigned data).

There is no provided main. Create the program source file based on the previous assignments. You may declare additional variables as needed.

Hint:

Pay close attention to the data types. The pSides[] array is word sized, the qSides[] array is double-word sized, the aSides[] array is byte sized, and the cSides[] array is doubleword sized.

Submission:

• All source files must assemble and execute on Ubuntu with yasm.

• Submit source files
  • 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 loss of up to 10%.

Scoring Rubric

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