Together this information forms a segment descriptor. 这些信息的集合构成了段描述符。
Instruction segment descriptor register 指令段描述符寄存器
Other than segment descriptor numbers, the contents of these registers are inaccessible to all software. 除了段描述符的号码以外,这些寄存器的内容对所有软件来说都是不可访问的。
A reference was made to a segment not present in memory ( one in which the Segment-Present flag of the Segment Descriptor was cleared). 引用一个不在内存中的段(段描述符的段存在标志为空)。
To use a given segment descriptor, its value is loaded into one of the segment registers. 要使用给定的段描述符,它的值需载入段寄存器中。
A segment including the default Local Descriptor Table ( LDT), usually shared by all processes ( see the next section). 一个保护默认LDT的段,通常被所有处理器共享。
The description checks with the photograph instruction segment descriptor register 这一描述与照片相符。指令段描述符寄存器
In order to update a segment register, the corresponding segment descriptor must be modified in kernel memory and then reloaded into the segment register. 更新段寄存器时,与其相应的段描述符必须在核心内存中修改,然后重新载入段寄存器。
A kernel device driver is designed to relocate the application's user-mode stack to the higher address and to modify the effective limit in the code segment descriptor, so the relocated stack is excluded from the code segment. 设计了一个内核驱动程序,将应用程序的堆栈移动到代码区的上部,并修改代码段的限长将堆栈区排除在代码段之外。
