System
Options-1 The System Options - 1 tab in the PCI Compiler wizard allows you to
specify the PCI-Avalon bridge’s device mode and performance profile.
1 When you select a device mode and performance profile, a brief
description displays just to the right of the selection, which can
help you determine the appropriate option for your system.
PCI Device Mode
There are three available device type modes. The wizard uses your
selections to define the operation of the targeted Altera device. For
example, if you want the targeted Altera device to operate as a target-only
peripheral, select the PCI Target-Only Peripheral.
This section defines the following PCI device type modes:
■ PCI Master/Target Peripheral
■ PCI Target-Only Peripheral
■ PCI Host-Bridge Device
PCI Master/Target Peripheral
This mode allows Avalon-MM master devices to access PCI target devices
via the PCI bus master interface, and PCI bus master devices to access
Avalon-MM slave devices via the PCI bus target interface.
Select this option if you are constructing an SOPC Builder system with:
■ Avalon-MM peripherals initiating accesses to PCI devices
■ PCI devices accessing Avalon-MM peripherals
■ The system Host processor located on the PCI bus side
