Avalon-MM Ports
The Avalon bridge is comprised of up to four (depending on device
operating mode) predefined ports to communicate with the interconnect.
This section discusses the four Avalon-MM ports:

Prefetchable Avalon-MM Master
The prefetchable Avalon-MM master port provides a high bandwidth
PCI memory request access to Avalon-MM slave peripherals. This master
port is capable of generating Avalon-MM burst requests for PCI requests
that hit a prefetchable base address register (BAR). You should only
connect prefetchable Avalon-MM slaves to this port, typically RAM or
ROM memory devices.
