The cache capacity of a computer storage system is 64B, each line is 8 bytes, and the direct mapping strategy is adopted. Initially there is no data in the cache and all lines have a valid bit of 0. When the CPU accesses the data at memory physical address 0x12, which part of the address space in memory will be loaded into which line in the cache, assuming the cache line number starts from 0?
某计算机缓存容量为64B，每一行8B，采用直接映射策略。初始时所有行没有数据，当CPU访问物理存储地址0x12时，哪段存储空间将被装载到缓存的哪一行？假定缓存的行号从0开始编号。
A、Data at memory address 0x12 ~ 0x19 is loaded into cache line 1
存储地址0x12 ~ 0x19的数据装载到缓存的行1
B、Data at memory address 0x12 ~ 0x19 is loaded into cache line 2
存储地址0x12 ~ 0x19的数据装载到缓存的行2
C、Data at memory address 0x10 ~ 0x17 is loaded into cache line 1
存储地址0x10 ~ 0x17 的数据装载到缓存的行1
D、Data at memory address 0x10 ~ 0x17 is loaded into cache line 2
存储地址0x10 ~ 0x17 的数据装载到缓存的行2
