A question about cache

Jing Bai
Intellectual 650 points

hi  sirs,

I am using C6657. My question is that could Core1's LL2 cache in Core0's L1D?

If yes, could you please give me some hints or sample?

ps:

I run project A on Core1 with data section in Core1's LL2. And I use Core0 to trace project A's data which int Core1's LL2.

If Core1's LL2 could cache in Core0's L1D, Core0 could trace the data by setting the coherency between them I think.

Am I right?

Thank you in advance.

regards,

Bai

    Hi Bai,

    Each L1D cache can cache it's own L2 data which means that Core #0 LID cash can cache Core #0 L2 data and Core #1 LID cash can cache Core #1 L2 data, whche means that Core #0 L1D will not cache Core #1 L2 data,

    Thanks,

    HR
