4.3.3.1. DTI Interface for TCU

The Distributed Transaction Interface (DTI) is new to MMU-600. This interface manages communication between the Translation Buffer Unit (TBU) and the Translation Control Unit (TCU) using the DTI protocol. The DTI protocol runs on top of an AXI4-Stream interface.

The TCU has a subordinate DTI interface. It has both manager and subordinate AXI4-Stream interfaces to facilitate the bi-directional communication with the TBUs.
