文档介绍：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，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-speedcalculationsand fast input/output 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 microcontrollersinengine-controlsystems, 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-effectivecontrollerwith a lowinterrupt latency response, ability to service the high number of time and event drivenintegrated peripheralneeded in real time applications, andC^U with above averagepro
