Thin Links slave interface in non-coherent mode
The following figure shows the Thin Links TLX-400 AXI slave interface on the Juno r2 SoC, that is the
slave interface in non-coherent mode, and its connection to the Thin Links TLX-400 master interface on
the LogicTile daughterboard.

Figure 2-9 Thin Links non-coherent, AXI slave interface
Note
• Non-coherent mode is the default mode of the Thin Links slave interface.
• The Thin Links non-coherent AXI slave interface uses one fewer control bit than the ACE interface
in each direction, and one more data bit than the ACE interface in each direction.
