摘要：浙江大学网络实验室原有的单片机实验系统只支持连续执行用户汇编程序的功能，在此基础上，提出了一种将单步功能程序段嵌入用户程序的单步调试技术。在单步执行用户程序主程序段前将外部中断位寄存器软件清零，通过软件方式触发外部中断，在中断程序中，将特殊功能寄存器的值通过串口发送给控制机，控制机再将该组数据通过中心服务器转发到用户终端，结合用户终端程序可以对用户程序的主程序段进行单步调试。

Abstract: A step debugging technique for Netlab single chip experiment system was proposed. The proposed method was a further development of the experiment system. Users could debug their main assembler code step by step in remote experiment environment. The external interrupt was used for proposed debugging function and it was triggered, using software method but not in common means. Inside the interrupt service routine, the values of the special function register were transmitted to control machine through serial port. All the data of the registers were collected and retransmitted to user client by center service broker. Users could debug their main code together with the terminal software client.
Key words: single chip computer; step debugging; Netlab; AT89S52
