CS201 Lab: Arithmetic Operations and Debugging

Objective of this lab: 


	To investigate Arithmetic Operations and implement them in Spim.

Preparation


	Read lab lecture notes.

Lab Assignment

Program#1:

Write a SPIM assembly language program convertF2C.s.
The program will do the following:
  1. Prompt the user to enter a temperature in Fahrenheit
  2. Convert it to Celsius
  3. Print out the converted values of the input 100, 0, and 70 with appropriate message
Here are the two formulas for your reference. 
 

	F = (9 * C / 5) + 32
	
	C = 5 * (F - 32) / 9

Program#2:

Write a SPIM assembly language program equation.s based on the example program math1.s in the lab notes.
The program will do the following:
  1. Prompt the user to enter a value for X
  2. Calculate the result of A*X^2+B*X+C, keep A, B and C values the same as before.
  3. Print out the calculated results of the input value 7, 5, and 9 with appropriate message

You will hand in the following:

  1. The source code in the file convertF2C.s and equation.s
  2. Display the program code in .pdf
  3. The screenshot to show the screen right after you loaded the .s file.
  4. The screenshot of the console displaying the results
  5. You are asked to submit one .pdf file and all the .s files. If you miss any one of them, you will get 0 marks.

Please note:
To make it easier for marking, you are required to submit the following files:
  1. One .pdf file and all the .s file, they contain all the required components for the lab assignment.
  2. Missing any one of the files (.pdf or .s files) you will get zero for the assignment.
  3. Submitting with other file format such as .zip or .doc, you will lose 5 marks.
  4. This will apply to Lab #6 to Lab #9.
