表 2 描述了主要的寻址形式。 表 3 给出了命令。
The major forms of addressing are described in Table 2. Commands are given in Table 3.
这里使用内存间接寻址模式(第31行)访问命令表,还使用了ESI(和EDI)中的偏移量和一个乘数。
Here, memory indirect addressing mode (line 33) is used to access the command table along with an offset in ESI (and EDI) and a multiplier.
寻址的页不在内存中,对应的页表条目是空的,或者是违背了页式管理的保护机制。
The addressed page is not present in memory, the corresponding page Table entry is null, or a violation of the paging protection mechanism has occurred.
