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为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减掉index 2 bit，所以3 bit tag 03/18 13:49
5F：→ ksix:打错,block address 01000,index 00, tag 010 03/18 13:49
