[問題] 98交大計組第三題

[decimal (好恐怖)]

Ａtwo-way set associative cache with 2-word blocks and

a total size of 16 words. (using LRU replacement)


假設 word address : 16

binary address: 010000

則 他的 block address 為多少？

tag 跟 index 又是幾bit呢？？？

→ ssccg:1 bit offset in block，block address = 01000
→ ssccg:16 words → 8 blocks → 4 set，所以index為2 bit
推 ksix:block offset 1 bit,block address 0100,index 00,tag 01
→ ssccg:5 bit address減掉index 2 bit，所以3 bit tag
→ ksix:打錯,block address 01000,index 00, tag 010
