二、微机开发系统由于微电子技术的发展,传统的开发工具,甚至象逻辑分析仪都已经不够用了。微处理机系统的产品开发包括硬件开发和软件开发。软件开发不是逻辑分析仪所能做的,硬件开发也由于电子器件集成度的提高,使某些信号已不再可能从器件的引脚上得到。突出的例子是单片微处理机系统,其中的许多信号,如中断、定时,甚至地址、读/写等都不能在引出脚上测得。此外,在微处理机系统的调试中,内部寄存器的内容对调试是十分重要的,它们亦不能从引出脚上测得。 Second, the computer development system due to the development of microelectronics technology, the traditional development tools, and even logic analyzers are not enough. Microprocessor system product development includes hardware development and software development. Software development is not what logic analyzers can do, and hardware development is also making it impossible for certain signals to get from the pins of the device due to the increased level of integration of the electronics. Prominent examples are monolithic microprocessor systems in which many of the signals, such as interrupts, timing, even addresses, read / write, etc., can not be measured at the pinout. In addition, the debugging of microprocessor system, the contents of the internal registers for debugging is very important, they can not be measured from the pin.
