On Versal devices CHI is available in System Cache to create a coherent cache for accelerators by connecting to CPM. Either coherency remains local or CPM uses CCIX, which allows transparent data sharing between the node and agents.

Similar to the CCIX only case, firmware is used to control all the negotiations in the system of choice.
