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

Figure 2-10 Thin Links ACE slave interface
Note
The Thin Links ACE slave interface uses one more control bit than the non-coherent, AXI interface in
each direction, and one fewer data bit than the non-coherent, AXI interface in each direction.
