一、引言最近几年单板机在工业自动化控制、数据采集处理、仪器仪表智能化以及科研、教学等方面得到了广泛的应用。但是,由于单板机本身的软、硬件资源十分有限,一般地说单板机的硬件系统不具备有硬拷贝和显示屏幕(CRT)等外设,软件系统也不具备编辑、汇编、反汇编等系统软件,使用者只能在机器语言级上进行程序的调试。尽管目前单板机的监控程序有了一些改进,但总的来说调试功能还是有限的,用户在使用中遇到的困 I. INTRODUCTION In recent years, the single-board machine in the industrial automation and control, data acquisition and processing, intelligent instrumentation and research, teaching and so has been widely used. However, since the software and hardware resources of the single-board computer are very limited, generally speaking, the single-chip hardware system does not have peripherals such as hard copy and display screen (CRT), and the software system does not have editing, assembly, disassembly, etc. System software, the user can only debug the program on the machine language level. Although the current single-chip monitoring program has some improvements, but in general the debugging function is limited, the user encountered in the use of sleepy
