Microprocessor / ASIC

A microprocessor is a programmable integrated circuit that executes instructions and performs calculations as the central processing unit (CPU) of an electronics system. An ASIC (Application-Specific Integrated Circuit) is a custom-designed integrated circuit optimized for a specific application or function, offering higher performance and lower power consumption than general-purpose processors for dedicated tasks. Within an Electronics Unit, these components provide computational power, control logic, signal processing, and system management capabilities.

Microprocessors operate by fetching instructions from memory, decoding them, and executing operations through arithmetic logic units (ALUs) and control units. ASICs implement fixed hardware logic designed for specific algorithms or functions. Both use semiconductor technology with transistors arranged to perform digital logic operations, processing binary data through electrical signals across integrated circuits.
