※ 引述《jerryr (灰色的苦涩 .....)》之铭言:
: Each page-table entry is usually 4 bytes long,
: but that size can vary as well. A 32-bit entry
: can point to one of 2(32) physical page frames.
: If a frame is 4 KB, then a system with 4-byte
: entries can address 2(36) bytes (or 64 GB) of
2(44) bytes 16 TB
20 + 12
^这个对映到2(32)
所以是32+12=44
: physical memory.
: Note: 2(32) 表示 2 的 32 次方 ....
: 请问一下...
: 关于下面那个 2 的 36 次方 我怎样也算不出来.... :(
: 有人可以告诉我 怎么算的吗 ....
: 谢谢
