英文翻译 原文： 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 addition, there are so-called "break system", the system is a "janitor" role, when the microcontroller control object parameters that need to be intervention to reach a particular state, can after this "janitor" communicated to the CPU, so that CPU priorities of the external events to take appropriate counter-measures. Microcontrollers are used in a multitude of commercial applications such as modems, motor-control systems, air conditioner control systems, automotive engine and among 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 future microcontrollers. The environment was developed in conjunction with Microsoft Foundation Classes (AT89C51). The paper describes the design and mechanism of this test environment, its interactions with various hardware/software environmental components, and how to use AT89C51. Are 8-bit microcontroller early or 4 bits. One of the most successful is the INTEL 8031, for a simple, reliable and good performance was a lot of praise. Then developed in 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

the Real-Time Clock Based on AT89S51 Author: Class: ; Name: Abstract: Digital clock has become indispensable in people's daily life, it is widely used in public places such as the family and the office, and it gives people great convenience in study, work and entertainment. Due to the development of digital integrated circuit technology and the advanced quartz technology, the digital clock has advantages of accurate, stable performance and easy to carry. It is also used in automatic control, automatic signal and etc. Although the digital clocks are already sold on the market, but the single chip microcomputer timer function also can complete the design of the digital clock circuit. So it is necessary to the design of the digital clock. By single chip microcomputer internal timer timing precision, the four digital tube display year, month, day, time, minutes and seconds. With the keyboard, users can be preset time, display the time, set the content, set time operation mode, etc. Keywords: AT89S51; clock; digital tube; keyboard switch; function Introduction: AT89S51 is a very suitable for the beginners of the single chip microcomputer, it is fully compatible with the traditional instruction system of 8051,8031. Can realize the following functions: 1. Use the keyboard switch, show respectively the seconds, minutes, hour, day, month, year; 2. Use the keyboard preset year, month, day, time, minutes and seconds; 3. Can the countdown, the countdown units for minutes; 4. Every second , the four decimal point shine once; 5. Timing alarm clock function, a buzzer call reminder. 6. The clock error daily is not more than 1 second. Methods: 1.The minimum single chip microcomputer system AT89S51 has the following standard functions: 8 k bytes Flash, 256 bytes RAM, and 32-bit I/O lines, a watchdog timer, two data pointer, three 16 timer/counter, a level 6 vector 2 interrupt structure, full duplex serial port, piece of crystals and the clock circuit . In idle mode, the CPU stops working, allows RAM, timer/counter, serial port and interrupt continue to work. In fall protection mode, RAM content are stored, has been frozen, single chip microcomputer stops all work, until the next interruption or hardware reset.
