8086 Assembly Workshops









Overview

This series of workshops explores core programming concepts and techniques in 8086 assembly language. Throughout these exercises, I have developed a deeper understanding of low-level programming, memory manipulation, and algorithm design. The workshops focus on implementing basic and intermediate routines that enhance both logical thinking and knowledge of computer architecture.

What I Learned

Control Flow with Loops and Conditions

I learned to create and manage loops using instructions like loop, and how to implement conditional checks with comparison (cmp) and jump instructions (je, jne). This allows efficient control over program flow and decision-making.

Arithmetic Operations and Register Management

Working with 8086 assembly reinforced my ability to perform arithmetic operations using instructions like add, sub, and div. Managing data across different registers (ax, bx, cx, dx, etc.) while considering byte- and word-sized values became a crucial skill for handling data effectively.

Memory Manipulation and Array Processing

I gained experience in working with memory segments and pointers (ds, si, bx). I learned to copy data between segments, manipulate memory addresses, and perform operations on arrays, such as sorting and summing, by incrementing and comparing pointer values.

How to Run the Programs

To execute these programs on an 8086 simulator or emulator, follow these steps:

Setup Your Environment

  • Install an 8086 emulator like EMU8086 or DOSBox if not running on original hardware.

Assemble the Code

  • Open your emulator or assembler tool and create a new assembly file (.asm).
  • Copy the desired program code into the file.

Compile the Program

  • Use the assembler’s "Compile" or "Assemble" function to generate the machine code (.com or .exe).

Run the Program

  • Execute the compiled file in the emulator.
  • Monitor the output or register changes directly within the emulator interface.

Debug and Analyze

  • Use debugging tools in your emulator to step through the program. Observe register and memory changes to verify that the program behaves as expected.

Requirements

  • 8086 Emulator: EMU8086, DOSBox, or any compatible tool.
  • Assembler: Built-in assembler with the emulator or an external assembler like TASM or MASM.
  • Basic Assembly Knowledge: Familiarity with instructions, registers, and memory addressing.

Conclusion

These workshops have provided hands-on experience with 8086 assembly language programming. Through working with loops, conditionals, memory manipulation, and arithmetic operations, I have built a stronger foundation in low-level programming and computer architecture. This knowledge is invaluable in understanding how modern computing systems function at their core.

  Multispectral Imaging in MATLAB https://github.com/diegodl11/Multispectral-Imaging-.git Introduction This project focuses on implementing and visualizing multispectral imaging techniques using MATLAB. Multispectral imaging captures information from multiple wavelengths across the electromagnetic spectrum, unlike traditional RGB images that capture only three bands. These images can be used for applications in agriculture, medical imaging, and remote sensing, among other fields. Project Overview This project uses MATLAB to load, process, and visualize multispectral images from different bands. It implements techniques for image filtering, contrast enhancement, and visual inspection of various bands, allowing users to observe features like vegetation health, water presence, and more. Prerequisites MATLAB installed with the Image Processing Toolbox. A multispectral image file (preferably in  .tif  format with multiple bands). How to Run the Code Load the Image : The path t...
