Based on the reference BF535 PUB schematics, we noticed that there is
the Intel's PCI_to_PCI
bridge (21152) between the ADSP-BF535 and the PCI connector. Is there any
reason to
use it? Can we connect to the host directly  (e.g to the PCI bus connector on
the PC mother board)?

 

 

The PCI-to-PCI bridge is used only as voltage translator, because as you know
the BF535 uses 3.3 V signaling for its I/O pins while most computers PCI busses
are 5 V.  The bridge does automatic voltage sensing and as such you can connect
the board to either 3.3 V or 5 V systems.
