Consider a computer system with both segmentation and paging. When a segment is in memory, the space overhead of the segment comes from two sources: internal fragmentation and page table entries for the segment. Assume that the segment size is s, and each page table entry occupies 8 bytes. What page size (in bytes) minimizes such overhead? 這一題要怎麼算啊?? 不懂內部碎裂要怎麼假設ㄝ.... 有勞高手指點一下~~ 鋼溫!! -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 223.139.197.100
kane9988:如果要使overhead最小,則page table大小和內部碎裂加起來 11/01 00:45
kane9988:要剛好一個page,好像是在os恐龍裡面看到的 11/01 00:46
kane9988:所以假設頁框大小為n,(s/n)*8=n/2 11/01 01:04
