因为研究生复试的需要所以最近折腾了下8086的汇编,
不过proteus总是没有我预期的完美[可能也跟和谐的版本有关]
下面是折腾8259的一些总结,不过有一些问题,希望知道的能予以指正 
电路搭建,基于自带的例子 (原文件名:8259_1.png) 
程序源码 (原文件名:8259_2.png) 
断点设置 (原文件名:8259_3.png) 
仿真1 (原文件名:8259_4.png) 
仿真2 (原文件名:8259_5.png)
另外,一些问题罗列如下
-.我用的老王的77sp2和谐,不过逻辑仿真器貌似用不了啊
-.8259模型需要改一下[加几个字符]才能用于仿真
0.一开始会莫名其妙的产生一个终端,一般位于前16字节,所以我的程序在那里也设置了捕获的proc,要不然会跑飞,不知为何
1.下一次触发时才会相应正确的中断,而当前相应的为上一次的?不过Simulation Log里的信息倒是正确的
2.级联模式,次级的irr不会自动清除,至少我觉的应该自动清除的,导致响应时会被进制,当然可能是我程序的问题
3.软件触发的中断没问题,直接int xx出来的中断都可以正确的响应,个人感觉要么是我程序的问题,要么是8259模型的问题
4.Proteus中仿真用exe和com格式的都可以,我的程序是使用masm的,顺带试了下mingw套件里的gas汇编,com格式输出时也是可以的
不过没法调试,即使-gstabs加上了也不行.
*.上面的问题可能是本人程序上的错误,希望熟悉8086汇编的人能指正一下
