Study Notes
Overview of CPU Architectures: X86, X64, and ARM
- The CPU (Central Processing Unit) is responsible for executing program code in a computer and performs basic operations on instructions.
- The CPU operates in a sequence of fetch, decode, execute, and store, retrieving instructions, deciphering them, performing the instructions, and saving the results.
- There are three main CPU architectures: X86, X64, and ARM.
- X86 is Intel's 32-bit instruction set architecture used in early PCs, with a progression from 8086 to 586 and later brand names like Celeron and Pentium. It is limited to addressing 4 GB of RAM due to its 32-bit architecture.
- X64 extends the X86 architecture to support 64-bit operations and can address more memory. It is commonly used in modern PCs and referred to as AMD64 or Intel 64 depending on the manufacturer.
- 32-bit systems can only run 32-bit programs, while 64-bit processors can run both 64-bit and 32-bit programs due to backward compatibility. X64 processors are widely used for compatibility and support.
- ARM stands for Advanced RISC Machines and is an architecture with a reduced instruction set. It was initially used in low-power devices like tablets and smartphones.
- Apple introduced ARM-based processors (M1 series) for desktops and laptops, offering extended battery life. ARM is also popular in system-on-a-chip (SoC) configurations for devices like smart TVs and smart speakers.
- RISC (Reduced Instruction Set Computer) architecture, like ARM, uses fewer instructions but relies more on code. RISC systems achieve the same tasks with less code, reducing power consumption and extending battery life.
- RISC and ARM-based processors are becoming more popular for various systems, including desktops and laptops.
- Windows 11 versions are starting to support ARM-based processors, expanding their usage.
