Understanding BX and BL in ARM Assembly In ARM assembly, BX (Branch and Exchange) and BL (Branch with Link) are essential for function calls and dynamic branching. BL(Branch with Link) What does BL do? Calls a subroutine (function). Saves the retu...
MOVEGE Instruction in ARM Assembly MOVGE is a conditional move instruction in ARM assembly. It stands for: MOVGE → MOVE if Greater than or Equal MOVGE Rd, Rn moves the value of Rn into Rd only if the condition "Greater than or Equal (GE)" is met....

Introduction In this project, I modified a 6502 Assembly program originally designed for addition and turned it into a subtraction calculator. I used and adapted code from Krins Kumar’s blog post. This post satisfies that requirement by clearly label...
This is the third article about the quantitative practice of DEX exchanges. In this article, we will introduce the user guide of the Vertex protocol. Preface In the framework of traditional decentralized exchanges (DEX), quantitative traders often n...
Compiler Optimizations? Sounds complicated and advanced right? Do not worry this is why this article exist to help you and I get a better understanding of compiler optimizations. In addition, I’ll go over what 64-bit systems are as well briefly. Howe...
Mastering Assembly Language: The Foundation of Low-Level Programming Assembly language is one of the most fundamental programming languages, serving as a bridge between high-level programming and machine code. It provides developers with direct contr...
Comprehensive Guide to Operating System Development: Kernels, Compilers, and Beyond Operating system (OS) development is one of the most complex yet rewarding fields in computer science. It involves creating the foundational software that manages har...
Our project is a basic calculator that does the following: Clears the screen using a ROM routine. Displays a title (“Calculator”). Prompts the user to enter two numbers (each from 0 to 99). Adds the two numbers together using Binary-Coded Decimal...
