CPU

The central processing unit — the sequential instruction executor at the heart of every programmable system.

Fetches, decodes, and executes one instruction stream per core

Arithmetic happens in the ALU, operands live in register files.

Shared-state coordination requires mutex primitives.

In embedded contexts, often an ARM core inside a MCU or SoC
