51 Microcontroller Introduction

Microcontrollers basic component is a central processing unit (CPU in the

computing device and controller), read-only memory (usually expressed as a ROM),

read-write memory (also known as Random Access Memory MRAM is usually expressed

as a RAM) , input / output port (also divided into parallel port and serial port, expressed

as I / O port), and so composed. In fact there is also a clock circuit microcontroller, so

that during operation and control of the microcontroller, can rhythmic manner. In

others. The high processing speed and enhanced peripheral set of these microcontrollers

make them suitable for such high-speed event-based applications. However, these critical

application domains also require that these microcontrollers are highly reliable. The high

reliability and low market risks can be ensured by a robust testing process and a proper

tools environment for the validation of these microcontrollers both at the component and

at the system level. Intel Platform Engineering department developed an object-oriented

multi-threaded test environment for the validation of its AT89C51 automotive

microcontrollers. The goals of this environment was not only to provide a robust testing

environment for the AT89C51 automotive microcontrollers, but to develop an

environment which can be easily extended and reused for the validation of several other

8031 out of MCS51 MCU Systems. SCM systems based on this system until now is still

widely used. With the increased requirements of industrial control field, began a 16-bit

microcontroller, but not ideal because the cost has not been very widely used. After 90

years with the great development of consumer electronics, microcontroller technology

has been a huge increase. With INTEL i960 series, especially the later series of widely

used ARM, 32-bit microcontroller quickly replace high-end 16-bit MCU status and enter

the mainstream market. The traditional 8-bit microcontroller performance have been the
