[自制简单操作系统] 3、内存管理和窗口叠加

 

 

 

1、本次主要进展

>_<" 这次主要学习了系统内存管理和窗口叠加~由于上两篇都做了详细的框架说明和介绍,这里直接上代码!


 

2、文件及函数构成

>_<" 这里和第二篇相比,把鼠标和键盘的相关函数独立出来放进各自相应的文件中,并主要在内存管理和窗口叠加进行探索,同时还有部分代码整理~

PS: 这里因为多了几个.c文件,所以makeFile中OBJS_BOOTPACK要把他们加进来~

OBJS_BOOTPACK = bootpack.obj naskfunc.obj hankaku.obj graphic.obj dsctbl.obj int.obj fifo.obj keyboard.obj mouse.obj memory.obj sheet.obj

PS: 为了整体清晰,上面的结构图把bootpack.h和字库文件没有列入~

 71 ;    并将高位置0,低位置1,再将这个值返回给CR0,这就完成了模式转化,进入到不用颁的保护模式。
 72 ; CR0是control register 0是一个非常重要的寄存器,只有操作系统才能操作它
 73 ; protected virtual address mode 受保护的虚拟内存地址模式,在该模式下,应用程序不能随便改变段的设定,又不能使用操作系统的段。操作系统受CPU保护
 74 ; 在保护模式中主要有受保护的16位模式和受保护的32位模式,我们要使用的是受保护的32位模式
 75 ; 在讲解CPU的书上会写到,通过带入CR0而切换到保护模式时,马上就执行JMP指令。所以我们也执行这一指令。为什么要jmp呢?因为变成保护模式后,机器语言的解释发生变化,
 76 ; CPU为了加快指令的执行速度而使用了管道(pipeline)这一机制,也就是说前一条指令还在执行时,就开始解释下一条甚至是再下一条指令,因为模式变了就要重新解释一遍,so..
 77 ; 而且在程序中,进入保护模式后,段寄存器的意思也变了(不是*16再加算的意思),除了CS以外所有的段寄存器的值都从0x0000变成了0x0008.CS保持不变是因为CS如果变了就乱了

 90 ;1) 这个函数用来指定的段上限和地址赋值给GDTR的48位寄存器,这是个很特殊的寄存器,并不能用MOV来直接赋值
 91 ;,唯一的方法就是指定一个内存地址,从指定的内存地址读取6字节(也就是48位),然后赋值给GDTR寄存器。完成这一任务的指令就是LGDT
 92 ;2) 该寄存器的低16位(即内存的最初的2个字节)是段上限,它等于“GDT的有效的字节数-1”,剩下的32位,代表GDT的开始地址
 93 ;3) 这里2个参数是ESP+4和ESP+8里存放,而我们要的是6字节形式的,所以要转换为我们想要的形式~
