👨💻 This repository contains a collection of MIPS assembly language programs I developed during my studies in the Computer Organization course (20471) at the Open University of Israel in 2022a. These programs are crafted to demonstrate the versatility and practical applications of assembly programming in various domains.
🚀 Each program in this collection showcases unique functionalities, ranging from number systems and string manipulation to linked list operations in assembly language. Notably, the programs q2 and q3 were part of my course assignments and earned a perfect score of 100. The program SumAndConvertInput was developed later as a personal project, improving q2 to handle user input, while exploring the intricacies of assembly programming.
📚🖥️ These projects serve as an excellent resource for educational purposes, offering insights into the intricacies of assembly language. Whether you're a student, a hobbyist, or someone curious about low-level programming, these programs provide a hands-on experience to deepen your understanding of assembly language.
Enjoy exploring the features and functionalities of these assembly language programs! Dive into the world of programming and discover the power of MIPS assembly language.

SumAndConvertInput is a versatile assembly program designed to process a list of user-input integers. This program offers functionalities including summing all entered numbers, calculating the sum of negative numbers, and converting each number in the list to its quaternary (base-4) representation. It's an excellent tool for educational purposes and for those interested in number systems and their conversions.
- Sum Calculation: Compute the sum of all entered integers.
- Negative Sum: Calculate the sum of only the negative numbers in the list.
- Quaternary Conversion: Convert each number in the list to its equivalent in the quaternary numeral system.
- Compile the program using a MIPS assembler.
- Run the compiled program.
- Input numbers as prompted (end input with
-9999). - View results for sum, negative sum, and quaternary conversion.
q3 identifies the most common letter in a static string, deletes its occurrences, and allows for iterative processing on the modified string.
- Finding the Most Common Letter: Identify the most frequently occurring letter in a predefined string.
- Lexicographic Ordering: Display string characters in lexicographic order based on their occurrence count.
- Interactive Deletion: Restart the program with the modified string for continuous processing.
- Compile the program with a MIPS assembler.
- Run the compiled code in a MIPS-compatible simulator or environment.
- Observe outputs for the most common letter, lexicographically ordered string, and deletion functionality.
The following example demonstrates the program's functionality for the string "AEZKLBXWZXYALKFKWZRYLAKWLQLEK", which has the most common letter "L". Notice that the program restarts with the modified string after each deletion.
q2 operates on a predefined linked list of integers, computing their sum and converting them to quaternary numeral system representation.
- Summing Numbers: Calculate the sum of all integers in the linked list.
- Summing Positive Numbers Divisible by 4: Sum positive numbers in the list divisible by 4.
- Quaternary System Representation: Convert and display each number in the list to its quaternary equivalent.
- Compile the program using a MIPS assembler.
- Run the compiled code in a MIPS-compatible environment or simulator.
- Observe the outputs for total sum, sum of positives divisible by 4, and quaternary representation.
- MIPS architecture (or an emulator like MARS MIPS simulator).
- Basic understanding of assembly language.
