5. Under the Avalon-MM System Settings heading, specify the settings in Table 3–6.
6. Under the Avalon-MM to PCI Express Address Translation Settings, specify the
settings in Table 3–7.
Refer to “Avalon-MM-to-PCI Express Address Translation Algorithm for 32-Bit
Addressing” on page 7–23 for more information about address translation.
7. Click Finish.
8. To rename the Cyclone Hard IP for PCI Express, in the Name column of the
System Contents tab, right-click on the component name, select Rename, and
type
DUT
r
1 Your system is not yet complete, so you can ignore any error messages generated by
Qsys at this stage.
1 Qsys displays the values for Posted header credit, Posted data credit, Non-posted
header credit, Completion header credit, and Completion data credit in the message
area. These values are computed based upon the values set for Maximum payload
size and Desired performance for received requests.
Adding the Remaining Components to the Qsys System
This section describes adding the DMA controller and on-chip memory to your
system.
1. On the Component Library tab, type the following text string in the search box:
DMA r
Qsys filters the component library and shows all components matching the text
string you entered.
2. Click DMA Controller and then click +Add. This component contains read and
write master ports and a control port slave.
