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？？？

1F：→ ssccg:1 bit offset in block，block address = 01000 03/18 13:48
2F：→ ssccg:16 words → 8 blocks → 4 set，所以index為2 bit 03/18 13:48
3F：推 ksix:block offset 1 bit,block address 0100,index 00,tag 01 03/18 13:48
4F：→ ssccg:5 bit address減掉index 2 bit，所以3 bit tag 03/18 13:49
5F：→ ksix:打錯,block address 01000,index 00, tag 010 03/18 13:49
