Microprocessor, micro computer, micro processor, the CPU, microcontroller, embedded processor, respectively are different concepts, difference is very big, in particular:

A microprocessor, it is to point to by one or a few pieces of large scale integrated circuit of the central processor, the circuit has to perform the function of the control unit and the arithmetic logic unit, in real life, it is mainly used for mobile devices (e.g., smart phone),

Two, microcomputer, is one of the electronic computer, hereinafter referred to as "micro" or "computer", because it has the features of the human brain, so people also called it a "microcomputer, microcomputer is composed of large scale integrated circuit of the electronic computer, volume is small, it is based on microprocessor, and memory and input/output (I/0) within the interface circuit and the corresponding auxiliary circuit, constitute the bare-metal,

Three, microprocessor, refers to using large scale integrated circuit or microprocessor made of very large scale integrated circuit, memory and the input/output interface of form a complete set of computer,

Four, the CPU, the Central Processing Unit (CPU, Central Processing Unit) is a very large scale integrated circuit,

Five, MCU (Microcontrollers) is A kind of integrated circuit chips, is to use very large scale integrated circuit technology with data processing ability of the central processor, the CPU, RAM RAM, read-only memory ROM, A variety of I/O mouth and interrupt system, timer/counter function (may include display driver circuit, pulse width modulation circuit, analog multiplexer, A/D converter circuit) integration to A piece of silicon consisting of A small and perfect microcomputer system,

Six, embedded processor, is the core of the embedded system, is to control, auxiliary hardware unit of the system operation,
