Cortex-A7's L2 DCache问题

chinatiger

hi, experts:

CA7 CPU：

L2 DCache是一个unify type的DCache，并不区分Instruction and Data.

如果只Enable ICache：那么在预存取Instruction到L1 ICache的过程中，L2 DCache会参与进来吗？

best wishes,

    “L2 DCache”的说法并不确切，正确的术语是“L2 Cache”。

    > 如果只Enable ICache：那么在预存取Instruction到L1 ICache的过程中，L2 DCache会参与进来吗？

    是的，L2会参与进来的。
