AT89C51的概况(中文4500字,英文2500字)
1 AT89C51的应用:
单片机广泛应用于商业：比如调制解调器，电动机控制系统，空调控制系统，汽车发动机和其他一些领域。这些单片机的高速处理速度和增强型外围设备集合使得它们适合于这种高速的场合。然而，这些关键应用领域也要求这些单片机高度可靠。测试环境和用于验证这些元部件层次和系统级别的单片机的合适的工具环境保证了可靠性和低风险。Intel 平台工程部门开发了一种面向对象的用于验证它的 AT89C51 汽车单片机多线性测试环境。这种环境的目标不仅是为 AT89C51 汽车单片机提供测试环境，而且开发一种能够容易扩展并重复用来验证其他几种将来的单片机的环境。开发的这种环境连接了 AT89C51。本文讨论了这种测试环境的设计和原理，它的和各种硬件和软件环境部件的交互性，以及如何使用 AT89C51。
The General Situation of AT89C51
1 The application of AT89C51
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. [来源：http://Doc163.com]
