Microprocessor chips (MPU) are silicon devices that serve as the central processing unit (CPU) in computers.

Specialty microprocessors and microcontrollers are specialty or proprietary products and accessories related to microprocessors and microcontrollers

Microprocessor and IC programmers, compilers and debuggers are programs that translate high-level language codes into assembly (machine) code, or track and correct errors (bugs) in program code

CPU coolers are integrated fans and heat sink assemblies packaged to provide optimum cooling performance, often for specific processors.

Digital signal processors (DSPs) are specialized microprocessors designed specifically for digital signal processing, usually in real-time.

Impedance matching networks are electrical circuits which, when connected between two networks, match the output impedance of the source (the first network) to the input impedance of the load (the receiving or second network).

Smart card chips contain a microprocessor and/or memory.
