The accelerator coherency port (ACP) is a 128-bit AXI interface to enable coherent transactions from the PL to snoop the APU L2 cache that includes write allocation into the APU L2 cache. The ACP does this by connecting to the snoop control unit (SCU) inside the APU MPCore.

The ACP interface is generally used for legacy applications but has other, general applications.
