What This Document Is
This is a homework assignment for EE 357, Basic Organization of Computer Systems, at the University of Southern California. It focuses on low-level programming concepts, specifically assembly language and stack operations within a simplified computer architecture. The assignment requires students to analyze and trace the execution of assembly code, predict register and memory states, and understand the relationship between high-level code structures and their assembly implementations. It also includes questions relating to processor status registers and exception handling.
Why This Document Matters
This assignment is crucial for students enrolled in EE 357 who are building a foundational understanding of how software interacts with hardware. Successfully completing this work will reinforce your ability to read, interpret, and debug assembly code – a skill valuable in embedded systems, operating systems development, and computer architecture research. It’s particularly helpful when preparing for more advanced coursework that builds upon these core principles. Students will benefit from working through this assignment after lectures covering assembly language, subroutine calls, stack frames, and interrupt handling.
Common Limitations or Challenges
This assignment does not provide a comprehensive introduction to assembly language programming. It assumes prior knowledge of basic assembly instructions and computer architecture concepts. It also doesn’t offer step-by-step solutions or a complete walkthrough of the code; rather, it challenges you to apply your understanding to analyze and predict program behavior. The assignment focuses on a specific assembly dialect and may not directly translate to other architectures without modification.
What This Document Provides
* Assembly code snippets for analysis, including labeled instructions and memory addresses.
* Specific tasks requiring the determination of register and stack contents at various points during program execution.
* A C-style subroutine and its corresponding assembly code for stack frame analysis.
* Questions relating to processor status register (SR) interpretation.
* A series of code examples involving TRAP instructions and exception handling.
* Clear submission instructions regarding formatting and expected output (hexadecimal representation).
