GIC-500 how connects to CPU cores?

GIC-500 how connects to CPU cores?

在GIC-500 中CPU Interface 是GIC的一部分还是cluster 的一部分?

  • The CPU Interface is part of the processor itself.  Practically speaking, it has to be as the CPU Interface registers are now accessed as system registers rather than memory mapped registers.

    The CPU Interface(s) in the processor connects to GIC-500 using AXI Stream interface.  The protocol used over this connection is described in the GICv3/GICv4 specification.
