Target Performance Profile
bridge’s master ports must be connected to this port. There is no internal
access inside the bridge from the PCI bus to these registers. You can only
read-from and write-to these registers from the interconnect.
Control/Status Register Module
The PCI-Avalon bridge provides a rich set of control and status registers
including mailbox registers. To access these registers, you must enable
the Control Register Access Avalon Slave port.
Mailbox Registers
The PCI-Avalon bridge provides two sets of mailbox registers. These
registers enable PCI and Avalon-MM masters to pass one DWORD of data
and assert an interrupt. To use the mailbox registers, you must enable the
Control Register Access Avalon Slave port.
One set of mailbox registers is used by external PCI masters. When a PCI
master writes a 32-bit value to a mailbox register, an Avalon-MM
interrupt is asserted. The number of available mailbox registers is
determined by the PCI-to-Avalon performance profile.
The second set of mailbox registers is used by Avalon-MM masters. When
an Avalon-MM master writes a 32-bit value to an Avalon-PCI mailbox
register, a PCI interrupt is generated. The number of Avalon-PCI mailbox
registers depends on the target performance profile. Refer to
PCI MegaCore Function
The PCI-Avalon bridge instantiates the appropriate PCI MegaCore
function per user specifications. For example, if you select 64 Bit PCI Bus
from the PCI Data Bus Width field (System Options - 2 tab), your system
will use a 64-bit MegaCore function. Refer to

To use the PCI-Avalon bridge you must license one of the Altera
PCI MegaCore functions.
