中断服务程序的关键是：1.保护进入中断时的状态，并在退出中断之前恢复进入时的状态。2.必须在中断程序中设定是否允许中断重入，即设置EX0位。 本例中使用了INT0中断，一般中断程序进入时应保护PSW，ACC以及中断程序使用但非其专用的寄存器。本例的INT0程序保护了PSW，ACC，2等三个寄存器并且在退出前恢复了这三个寄存器。另外中断程序中涉及到关键数据的设置时应关中断，即设置时不允许重入。本例中没有涉及这种情况。 实验开始时K8应在H（高电平）端，要产生中断时先拨向L（低电平）端再拨回H端。 -Interrupt service s key is: 1. the protection enters when the interrupt condition, and when the withdrawal interrupt before regains enters the condition. 2. must in the interrupt routine establish whether to permit the interrupt re-entry, namely establishes the EX0 position. in this example has used the INT0 interrupt, generally the interrupt routine enters when should protect PSW, ACC as well as the interrupt routine use but non-its special-purpose register. This example INT0 program protection PSW, ACC,2 and so on three registers, and restored these three registers before the withdrawal. Moreover in the interrupt routine involves to when the essential data establishment should close the interrupt, namely when establishment does

E-Bazaar Online Shopping System This project is to provide ease in the transaction of money for student and other faculty members in collage. In this project, we have tried to cover important things like given the new account, username password, for new students. Sending the request for the authentication of username and password, selecting the students’ order, verifying that order and then giving the receipt to student and that much money will be deducted from student’s accounts. The students are also informed about the low account balance after some specific low amount.

详细设计的目的就是指导编码,明确的说,就是将你的设计拿给不同的人去写编码，写出来的程序处理流程相同.后续的评审或者是有人接替你的工作，只要查看详细设计，就能清楚你当时是怎样设计这些流程的。-The purpose is to guide the detailed design codes, specifically, is that your design showed that different people to write code, written procedures for processing the same. Follow-up assessment or someone to replace your job, as long as View the detailed design, we can clearly understand how did you design these processes.
