The central processing unit (CPU) is the sequential instruction executor at the heart of every programmable system. It fetches, decodes and executes one instruction stream per core.

The central processing unit (CPU) is the sequential instruction executor at the heart of every programmable system. It fetches, decodes and executes one instruction stream per core.

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

Coordinating shared state requires mutex primitives.

In embedded contexts the CPU is often an ARM core inside an MCU or a SoC.
