Which of the following are true? (1)Write-allocate policy means when a cache write miss occurs, the written data are updated in the next level of memory. (2)There is no cache coherency problem for the write-through cache since the data are written into the next level of memory, and thus the data are consistent between the two caches. (3)A cache can be a shared or private. (4)A cache can use either vitural address ot physical address for its tag. 解答：(3)、(4) 怎麼看都怪怪的... 有高手可以幫我解答嗎@@ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 115.82.3.3
