Coprocessor

A coprocessor is a computer processor used to supplement the functions of the primary processor (the CPU). Operations performed by the coprocessor may be floating point arithmetic, graphics, signal processing, string processing, cryptography or I/O interfacing with peripheral devices.

Microprocessornoun

(computer hardware) the entire CPU of a computer on a single integrated circuit (chip).

Microprocessornoun

integrated circuit semiconductor chip that performs the bulk of the processing and controls the parts of a system;

Microprocessor

A microprocessor is a computer processor wherein the data processing logic and control is included on a single integrated circuit, or a small number of integrated circuits. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer’s central processing unit.
