Introduction to 8086 DOS Assembly & COA Tutor

The 8086 DOS Assembly & COA Tutor is designed to facilitate learning in two key areas: DOS-based 8086 Assembly language and Computer Organization & Architecture (COA). It serves as an educational tool to help students understand how low-level programming (specifically assembly language) interacts with computer hardware, focusing on 16-bit and 32-bit architecture, and Computer Organization fundamentals. The tutor is tailored to run within DOS emulation environments like DosBox, ensuring that students can compile and execute programs in a realistic and historical DOS setting. Additionally, it bridges assembly language learning with COA principles such as memory architecture, instruction sets, and the functioning of CPUs in modern systems.

Main Functions of the 8086 DOS Assembly & COA Tutor

  • 1. Teaching Assembly Programming

    Example Example

    A student can write a simple program to add two numbers using assembly language. The tutor explains how to translate high-level language operations into assembly, manage data using registers, and execute arithmetic operations like `ADD` and `SUB`.

    Example Scenario

    A beginner learns how to write an assembly program in DosBox, step by step, compiling and debugging a program that computes the sum of two integers.

  • 2. Illustrating CPU Instruction Execution

    Example Example

    Through COA-related guidance, the tutor can explain the instruction cycle, which includes fetching, decoding, and executing instructions. Using real-time examples, such as how an instruction moves from memory to the processor, students can visualize how a CPU works.

    Example Scenario

    A student interested in CPU architecture learns how an instruction is fetched from memory, decoded, and executed by the CPU in a controlled simulation.

  • 3. Explaining Memory Management

    Example Example

    The tutor helps students understand different memory models (segmented vs. flat memory) used in x86 systems. For example, understanding the differences between data segment and stack segment in a simple DOS application.

    Example Scenario

    A student examines how the stack operates during function calls in assembly language, gaining insights into how memory is organized and accessed by low-level code.

Ideal Users of 8086 DOS Assembly & COA Tutor

  • 1. Undergraduate Students in Computer Science or Engineering

    Students who are learning about low-level programming languages, such as assembly language, and basic computer architecture concepts.
