CPU (Central Processing Units) are the primary processing components within embedded processors and controllers, responsible for executing program instructions and coordinating system operations. They perform arithmetic and logical operations, manage control flow, and interface with memory and peripheral resources through defined system architectures.

This category covers CPU devices intended to serve as the core computing element of an embedded system, providing the instruction execution engine that enables higher-level control and processing functions.

• Core function: Instruction fetch, decode, and execution with system-level control.
• System role: Coordinates data movement and timing between processing, memory, and external interfaces.
• Scope: Standalone CPU components used as the central compute core in embedded designs.
