※ 引述《wsx02 ()》之銘言：
: 1GB of physical memory
1GB = 2^30byte => 30 bit address
: a physically indexed data cache with 64KB data and 256Byte bolcks
64KB / 256B = 256 bolcks
: a 32-bit virtual address space and the page size is 64KB
64KB = 2^16byte => 16bit page offset
32bit - 16bit = 16bit virtual page NO.
30bit - 16bit = 14bit physically page NO.
: fully associative TLB with 2 entries and the LRU replacement policy
: CPU data cache is direct mapped
direct map => tag:14bit index: 8bit offset: 8bit
physical address data cache hit/miss TLB hit/miss
0x2d45 e221 M M
0x350a 58a3 M M
0x2d45 e251 H H
0x350a 5a09 M H
0x0933 5add M M
0x350a 5aaa M H
0x2d45 e292 H M
應該是這樣吧
