Dear sirs,
I read ACE specification and ARM processor documents for ACP explanation. I always have some questions about ACP.
As soon as you know, ACP exists in SCU for data coherency.
Q1: The document says that ACP usually connects to a DMA or cryptographic engine, so why does it connect to them?
Q2: who starts ACP port to transfer data from where to where?
Q3: How does ACP implement coherency in multi-core processor?
Thanks.
