CPU Architectures Overview
Gain an understanding of common CPU architectures like x86, x64, and ARM, focusing on their register sets and instruction execution.
Welcome to CPU Architectures!
Welcome to the fascinating world of CPU architectures! Understanding how different CPUs are designed is crucial for anyone diving into reverse engineering.
Think of it as learning the 'native language' a computer speaks. Different CPUs speak different languages, and knowing them helps us understand their instructions.
What is a CPU Architecture?
A CPU architecture defines how a Central Processing Unit (CPU) is built and how it processes instructions. It includes:
- The instruction set (the commands the CPU understands)
- The number and types of registers (internal storage)
- Memory management rules
These elements dictate how software interacts with the hardware, which is key for analysis.
