※ 引述《jerryr (灰色的苦澀 .....)》之銘言:
: 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
^這個對映到2(32)
所以是32+12=44
: physical memory.
: Note: 2(32) 表示 2 的 32 次方 ....
: 請問一下...
: 關於下面那個 2 的 36 次方 我怎樣也算不出來.... :(
: 有人可以告訴我 怎麼算的嗎 ....
: 謝謝
