ARM64 Assembly Fundamentals: Memory and Registers

To write efficient low-level code or debug software effectively, you must understand where data lives and how the processor accesses it. This text-only course breaks down the critical distinction between high-speed CPU registers and main memory within the ARM64 architecture. You will transition from high-level programming concepts to a solid grasp of hardware execution. By exploring how instructions manipulate registers and access memory, you will gain the foundational knowledge needed to read ARM64 assembly, analyze program behavior, and debug low-level issues. What you'll learn: Understand the fundamental hardware differences between registers and main memory; Read and write basic ARM64 assembly instructions for data movement and arithmetic; Analyze how the processor utilizes the stack, heap, and register file during execution; Apply debugging techniques to inspect register states and memory addresses; Explore modern ARM64 features, including memory alignment rules and foundational security concepts. The course begins with essential hardware terminology and basic concepts before guiding you through practical assembly instruction patterns and debugging scenarios. You will read through clear explanations and structured code snippets to build a robust mental model of CPU execution. Designed for software developers, students, and aspiring systems programmers who are new to assembly language and ARM64 architecture, this course requires no prior hardware or low-level programming experience. Start your journey into the inner workings of computer systems and master the fundamentals of ARM64 data handling.
