单片机广泛应用于商业：诸如调制解调器，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事件应用场合。

然而，这些关键应用领域也要求这些单片机高度可靠。

健壮的测试环境和用于验证这些无论在元部件层次还是系统级别的单片机的合适的工具环境保证了高可靠性和低市场风险。

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 汽车单片机提供一种健壮测试环境，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。

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、软件环境部件的交互性，以及如何使用AT89C51Microcontrollers are used in a multitude of commercial applications such asmodems, motor-control systems, air conditioner control systems, automotive engine andamong others. The high processing speed and enhanced peripheral set of thesemicrocontrollers make them suitable for suchhigh-speedevent-based applications.However, these critical application domains also require that these microcontrollers arehighly reliable. The high reliability and low market risks can be ensured by a robusttesting process and a proper tools environment for the validation of thesemicrocontrollers both at the component and at the system level. Intel PlaformEngineering department developed an object-oriented multi-threaded test environment forthe validation of its AT89C51 automotive microcontrollers. The goals of thisenvironment was not only to provide a robust testing environment for the AT89C51automotive microcontrollers, but to develop an environment which can be easilyextended and reused for the validation of several other future microcontrollers. Theenvironment was developed in conjunction with Microsoft Foundation Classes(AT89C51). The paper describes the design and mechanism of this test environment, itsinteractions with various hardware/software environmental components, and how to useAT89C51.8 位AT89C51 CHMOS 工艺单片机被设计用于处理高速计算和快速输入/输出。

MCS51 单片机典型的应用是高速事件控制系统。

商业应用包括调制解调器，电动机控制系统，打印机，影印机，空调控制系统，磁盘驱动器和医疗设备。

汽车工业把MCS51 单片机用于发动机控制系统，悬挂系统和反锁制动系统AT89C51 尤其很好适用于得益于它的处理速度和增强型片上外围功能集，诸如：汽车动力控制，车辆动态悬挂，反锁制动和稳定性控制应用。

由于这些决定性应用，市场需要一种可靠的具有低干扰潜伏响应的费用-效能控制器，服务大量时间和事件驱动的在实时应用需要的集成外围的能力，具有在单一程序包中高出平均处理功率的中央处理器。

拥有操作不可预测的设备的经济和法律风险是很高的。

一旦进入市场，尤其任务决定性应用诸如自动驾驶仪或反锁制动系统，错误将是财力上所禁止的。

重新设计的费用可以高达500K 美元，如果产品族享有同样内核或外围设计缺陷的话，费用会更高。

另外，部件的替代品领域是极其昂贵的，因为设备要用来把模块典型地焊接成一个总体的价值比各个部件高几倍。

为了缓和这些问题，在最坏的环境和电压条件下对这些单片机进行无论在部件级别还是系统级别上的综合测试是必需的。

IntelChandler 平台工程组提供了各种单片机和处理器的系统验证。

这种系统的验证处理可以被分解为三个主要部分系统的类型和应用需求决定了能够在设备上执行的测试类型。

The 8-bit AT89C51 CHMOS microcontrollers are designed to handle high-speedcalculations and fast input/output operations. MCS 51 microcontrollers aretypically usedfor high-speed event control systems. Commercial applications include modems,motor-control systems, printers, photocopiers, air conditioner control systems, disk drives,and medical instruments. The automotive industry use MCS 51 microcontrollers inengine-control systems, airbags, suspension systems, and antilock braking systems(ABS). The AT89C51 is especially well suited to applications that benefit from itsprocessing speed and enhanced on-chip peripheral functions set, such as automotivepower-train control, vehicle dynamic suspension,antilock braking, and stability controlapplications. Because of these criticalapplications, the market requires a reliable cost-effective controller with a lowinterrupt latency response, ability to service the high number of time and event drivenintegrated peripherals needed in real time applications, and a CPU with above averageprocessing power in a single package. The financial and legal risk of having devices thatoperate unpredictably is very high. Once in the market, particularly in mission criticalapplications such as an autopilot or anti-lock braking system, mistakes are financiallyprohibitive. Redesign costs can run as high as a $500K, much more if the fix meansback annotating it across a product family that share the same core and/or peripheraldesign flaw. In addition, field replacements of components is extremely expensive, as thedevices are typically sealed in modules with a total value several times that of thecomponent. To mitigate these problems, it is essential that comprehensive testing of thecontrollers be carried out at both the component level and system level under worst caseenvironmental and voltage conditions.This complete and thorough validation necessitatesnot only a well-defined process but also a proper environment and tools to facilitate andexecute the mission successfully.Intel Chandler Platform Engineering group provides postsilicon system validation (SV) of various micro-controllers and processors. Thesystem validation process can be broken into three major parts.The type of the device andits application requirements determine which types of testing are performed on thedevice微机接口实现两种信息形式的交换。
