The APU cache-coherent interconnect (CCI) includes an AXI coherency extension (ACE) to the PL (S_ACE_FPD). This interface is an extension to the AXI protocol with two-way coherency between the APU L2-cache and a cache subsystem in the PL.

Coherency is further discussed in the Cache Coherent Interconnect chapter.
