This default ldt segment descriptor is stored in the gdt 這個(gè)默認(rèn)ldt段描述符存儲(chǔ)在gdt中。
By default it contains a null segment descriptor 默認(rèn)情況下,其中會(huì)包含一個(gè)空的段描述符。
The corresponding segment descriptor stored in the gdt has following values 存儲(chǔ)在gdt中的對(duì)應(yīng)段描述符的值如下:
Each segment descriptor is eight bytes long and represents a single segment in memory 每個(gè)段描述符長(zhǎng)8個(gè)字節(jié),表示內(nèi)存中的一個(gè)段。
A 13 - bit index that identifies the corresponding segment descriptor entry contained in the gdt or ldt 一個(gè)13位的索引,用來標(biāo)識(shí)gdt或ldt中包含的對(duì)應(yīng)段描述符條目
Each time a segment selector is loaded on to segment registers , the corresponding segment descriptor is loaded from memory into a matching non - programmable cpu register 每次將段選擇器加載到段寄存器中時(shí),對(duì)應(yīng)的段描述符都會(huì)從內(nèi)存加載到相匹配的不可編程cpu寄存器中。
Since a segment descriptor is eight bytes long , its relative address inside the gdt or ldt is obtained by multiplying the most significant 13 bits of segment selector by 8 由于一個(gè)段描述符的大小是8個(gè)字節(jié),因此它在gdt或ldt中的相對(duì)地址可以這樣計(jì)算:段選擇器的高13位乘以8 。
For example , if the gdt is stored at address 0x00020000 and index specified by segment selector is 2 , then the address of corresponding segment descriptor is equal to 0x00020000 例如,如果gdt存儲(chǔ)在地址0x00020000處,而段選擇器的index域是2 ,那么對(duì)應(yīng)的段描述符的地址就等于( 2 * 8 ) + 0x00020000 。
The ti table indicator flag that specifies whether the segment descriptor is included in gdt if the value is 0 ; if the value is 1 , then the segment descriptor is included in the ldt Ti ( table indicator )標(biāo)志指定段描述符是在gdt中還是在ldt中,如果該值是0 ,段描述符就在gdt中;如果該值是1 ,段描述符就在ldt中。
The segment descriptor entry contains both a pointer to the first byte in the associated segment represented by the base field and a 20 - bit value the limit field which represents the size of the segment in memory 段描述符條目中包含一個(gè)指針和一個(gè)20位的值( limit字段) ,前者指向由base字段表示的相關(guān)段中的第一個(gè)字節(jié),后者表示內(nèi)存中段的大小。
In memory addressing for Intel x86 computer architectures, segment descriptors are a part of the segmentation unit, used for translating a logical address to a linear address. Segment descriptors describe the memory segment referred to in the logical address.
