Subject: Procedures and floating-point operations
Project Programs (75%): You are required to write the following three programs:
Program 1: Practice Leaf Procedures (15 points)
Create a MIPS assembly code that reads three positive numbers a, b, and c as input parameters.
The code shall execute in MARS to prompt the user to enter three positive integers represented in
decimal, each separated by Enter key. The program shall find the minimum number that is not
equal to zero. Your program should print out the minimum number on the screen.
Output Sample
a b c Expected F
0 5 3 3
100 50 33 33
78 0 450 78
10005 2000 3500 2000
Program 2: Practice floating-point operations (30 points)
Create a MIPS assembly code that calculates the BMI for a person based on the following formula:
BMI = Weight (lbs)/Height(inches)2 x 703.
Please read the following requirements:
1. All data should be defined as single precision floating point data.
2. The code shall execute in MARS to prompt the user to enter the weight (in pounds) and
height (in feet).
3. Your program should convert feet into inches, then apply the inches value in the equation.
Please see the example below for clarification.
4. After the program calculates the BMI, the program should identify the person as underweight,

normal, or overweight based on the following conditions:
a. If BMI < 18.5, the person is underweight.
b. If BMI >= 18.5 and BMI <= 24.9, the person is normal weight.
c. If BMI >= 25.0, the person is overweight.
5. The program should continue by asking the user to input different numbers.
Example:
Assume, you are required to find the BMI and the status of a person whose weight is 150 lbs and
height is 5.5 feet using your program.
1. First, the program asks the user to input the weight in pounds and height in feet
2. After, the user inserted the weight = 150 lbs and height = 5.5 feet
3. The program converts feet into inches by following this formula: Inches = Feet x 12
4. Then, the program applies the inches and pounds in the BMI formula given above. BMI =
Weight (lbs)/Height(inches)2 x 703 = (150lbs/66inches2
) x 703 = 24.2.
5. Then, the program determines the user status, which is in this case it is normal. Below is a
sample of output.

Program 3: Practice non-leaf procedures and stacks (30 points)
Create a MIPS assembly code that calculates your total work time in hours. The work is calculated
based on number of homeworks and the number of exercises the person accomplishes per day.
There is an average time (in hours) to complete each homework and finish each exercise. For
example, a person completed three homeworks and two exercises in a day. The average time to
complete homework for this person is one hour and the average time to complete an exercise is two
hours. The total time to complete all work is 3 hws x 1 hour + 2 exercises x 2 hours = 7 hours. The
following C code is a program that calculate the average work time per day. You can use it as a
reference for you to write your MIPS assembly code.
Notes:
a. The program inputs are:
a. number of homeworks.
b. average time to complete each homework in hours.
c. number of exercises.
d. average time to complete each exercise in hours.
b. The program output is:
a. Total work time in hours.
c. Consider the inputs and output as positive integer numbers.
d. To insert the inputs, write a code to prompt the user to enter four positive integers
represented in decimal, each separated by Enter key.
e. You program should print out the total work time.
f. Remember you are required to use nested (non-leaf) procedure and stack to preserve the
return address

int hw_func (int num_hws, int avg_hours) {
int total_hw_time;
total_hw_time = num_hws x avg_hours;
return total_hw_time;
}
int exercise_func (int num_exercises, int avg_hours) {
int total_exercise_time;
total_exercise_time = num_exercises x avg_hours;
return total_exercise_time;
}
int total (int nhws, int hours, int nexercises, int ehours) {
int total;
total = hw_func (nhws, hours) + exercise_func (nexercises, ehours);
return total;
}
void main( ) {
int num_homeworks = 4;
int average_hws_hours = 1;
int num_exercises_per day = 2;
int average_exercise_hours = 2;
int total_time = total(num_homeworks, average_hws_hours,
num_exercises_perday, average_exercises_hours);
printf(“%d\n”, total_time);
}

Project Report (40%)
The project report will be graded out of 100, and the points will be distributed as following:
A. Professional preparation: Submit the report as typed document saved as a PDF.
B. Report Content (100 points):
You are required to provide the answers for the following numbered section headings:
1.0 Program Input/Output (20 points): Describe (or list) the inputs and outputs of each
program.
2.0 Program Design (20 points): Describe briefly how each code (program 1, program 2
and program 3) operates.
3.0 Symbol Table (20 points): Create a 2-column Table describing all Registers used
and their specific Purpose in the code, where each registeris listed on a separate row
and identified by register name $t0, $s0, etc., as well as any Labels used and their
purpose on separate rows. You may takethe table below as sample.
Registers Purpose & Labels
$a0 Argument of syscall to print string
: :
4.0Learning Coverage (20 points): Provide a list of at least 5 technical topics learned
from this project.
5.0 Test Results (20 points): Provide screen shot(s) of two 2 proper MIPS code
executions in MARS for your Test Plan inputs. To illustrate, you are required to
execute program 1, program 2 and program 3 at least 2 times and, in each time, you
enter different input sets, and you get different outputs. Take a screen shot of each
execution (“MARS Message” console) and include it in your report.
