The HP and HPC interfaces provide a high-performance datapath to the PS-DDR and the OCM memories. When using the HPC interface, requests from the PL to the PS-DDR go through the CCI which manages the APU MPCore cache coherent environment. These use-case topologies are shown in This Figure and are described in the following section.
