Lab 4 Mips Assembly Languageprogramming With Mars Ideproceduresthe P

Analyze the provided assignment instructions focusing on MIPS assembly language programming using the Mars IDE tool, specifically involving procedures for sorting three numbers in memory in ascending order. The task involves writing a MIPS program that includes a main segment and a procedure that sorts three numbers, utilizing registers and memory operations. You are instructed to assemble, run, and observe register and memory values, then record the final values of designated registers ($t0, $t1, $t2) after sorting. You must include your personal details, a screenshot of the program, the results and observations, answers to related questions, and references (if any) in your lab report.

Introduction:

Procedural programming is a fundamental concept in assembly language, allowing a programmer to break down complex tasks into manageable, reusable blocks of code. In the context of MIPS assembly language programming within the Mars IDE, procedures facilitate modularity and clarity, especially when performing operations like sorting multiple numbers. This report discusses a typical exercise involving writing a procedure to sort three numbers in ascending order, executing the program, and analyzing the results, aligning with educational objectives to familiarize students with assembly procedures, memory management, and register use.

Main Body:

Understanding the Assignment and Procedures in MIPS Assembly

The core purpose of the assignment is to develop a MIPS assembly program that sorts three numbers in increasing order utilizing a procedure. The process begins with setting up the environment in Mars IDE: creating a new file, writing the code, assembling, and executing it. The program must include a main segment that initializes data, calls a sorting procedure, and then displays or stores the sorted output in registers ($t0, $t1, $t2). The procedure encapsulates the logic for comparison and swapping to ensure the numbers are sorted in ascending order.

In MIPS, procedures are defined as separate code blocks, typically with labels and using the stack or registers to pass data. The key functions involve loading data from memory, comparing values, swapping if necessary, and returning control to the main program. Registers like $t0, $t1, and $t2 are generally used to hold the numbers for processing.

Implementing the Sorting Procedure

The procedure to sort three numbers involves multiple comparisons. For example, compare $t0 and $t1; if $t0 > $t1, swap their values. Repeat similar comparisons between $t1 and $t2, then $t0 and $t1 again if needed, until the three numbers are sorted in ascending order. The program uses branch instructions (e.g., bgt, blt) and swap operations to rearrange the registers’ values. After the procedure finishes, the sorted numbers reside in $t0, $t1, and $t2, ready to be stored or displayed.

Once the program executes correctly, the user observes the final register and memory values, confirms the proper sorting, and records these results for submission. The process exemplifies fundamental practices in assembly language programming, including data manipulation, flow control, and subroutine management.

Practical Considerations and Observations

During execution, careful tracking of register states and memory locations is essential. It’s recommended to record the initial data, the intermediate steps, and the final sorted order. Variations in the initial input can be used to verify robustness. The resulting final values in $t0, $t1, and $t2, after sorting, demonstrate correct implementation if the smallest value is in $t0 and the largest in $t2.

Moreover, understanding the importance of register conventions, stack usage for parameter passing, and procedure calls in MIPS improves comprehension of low-level hardware interactions. The assignment also provides an opportunity to practice debugging, problem-solving, and documentation skills, including capturing screenshots and describing observations.

Conclusion:

This procedural approach to sorting numbers in assembly language underscores the importance of modular structuring, flow control, and register management. Learning to write and execute such a program in the Mars IDE not only deepens understanding of MIPS architecture but also enhances problem-solving competencies essential for computer science students. Proper documentation, including screenshots, observations, and analysis, ensures comprehensive learning and reflection on assembly programming practices.
