Parameters Legal Values Description
Size of Address Pages 12–27 The supported address size (in bits) that can be
assigned to each map number entries.
Prefetchable BAR On or Off Turning this option On invokes a Prefetchable Master
(PM) Bar in the PCI system. This option allows PCI-
Avalon Bridge Lite to accept and process PM transac‐
tions.
Prefetchable BAR
Size
10–31 The allowed reserved address range supported by the
PM BAR. The reserved memory space is 1 KByte (10
bits) to 4 GBytes (31 bits).
Prefetchable BAR
Avalon Address
Translation Offset
<BAR
translation
value>
The direct translation of the value that hits the BAR
and modified to a fixed address in the Avalon space.
Refer to the PCI-to-Avalon Address Translation
section.
Non-Prefetchable
BAR
On or Off Turning this option On invokes a Non-Prefetchable
Master (NPM) Bar in the PCI system. This option
allows the PCI-Avalon Bridge Lite to accept and
process NPM transactions.
Non-Prefetchable
BAR Size
10–31 Specifies the allowed reserved address range supported
by the NPM BAR. The reserved memory space is 1
KByte (10 bits) to 4 GBytes (31 bits).
Non-Prefetchable
BAR Avalon Address
Translation Offset
<BAR
translation
value>
The direct translation of the value that hits the BAR
and modified to a fixed address in the Avalon space.
Refer to PCI-to-Avalon Address Translation.
I/O BAR On or Off Turning this option On enables an I/O BAR in the
system. This option allows PCI-Avalon Bridge Lite to
accept and process I/O type transactions.
I/O BAR Size 2–8 The allowed reserved address range supported by the
I/O BAR. The reserved memory space is 4 bytes (2
bits) to 256 bytes (8 bits).
I/O BAR Avalon
Address Translation
Offset
<BAR
translation
value>
The direct translation of the value that hits the BAR
and modified to a fixed address in the Avalon address
space. Refer to PCI-to-Avalon Address Translation.
Maximum Target
Read Burst Size
1, 2, 4, 8, 16, 32,
64, or 128
Specifies the maximum FIFO depth that is used for
reading. Larger values allow more reads to be read in a
single transaction but also require more time to clear
the FIFO content.
Device ID <register value> Device ID register. This parameter is a 16-bit hexadec‐
imal value that sets the device ID register in the
configuration space.
Vendor ID <register value> Vendor ID register.This parameter is a 16-bit read-
only register that identifies the manufacturer of the
device. The value of this register is assigned by the PCI
Special Interest Group (SIG).
