一、前言自从把计算机的中心部分运算控制器集成于一块芯片上制成第一个微处理机以来,已经历了大约十年的岁月。这种硅片的价格到目前已降低到数百日元一片的程度,它作为一个独立的元件而便于得到广泛的应用,因此大量的测试装置内藏有微型计算机。但是微型计算机所具有的更大魅力之一在于使用者可以自编程序,这使测试装置有可能用于原来所不能的特殊用途。不仅如此,还可以实现对测试对象的控制或顺次改变参数的设定值而实现系统的自 I. INTRODUCTION Since the first microprocessor was built by integrating the central part of the computer’s controller into a single chip, it has been around for about a decade. The price of such a silicon wafer has so far been reduced to a few hundred yen. It is widely used as a stand-alone component so that a large number of test devices include a microcomputer. However, one of the more attractive features of microcomputers is that they can be programmed by the user, making it possible for the test device to be used for special purposes that were not available. Not only that, but also can achieve the control of the test object or to change the set value of the parameters in turn to achieve the system since
