Shown on this slide is the block diagram. The transceivers which also can be used for non-PCI express applications are shown on the right. The interface to the hard IP block supports a PIPE 2.0 compliant interface. This hard IP PCI express block offers support for endport and rootport applications and, as can be seen, implements a complete protocol stack. If the customer needs the flexibility, different layers can be bypassed as shown in the block diagram, e.g. for an application which needs a custom solution for the transaction layer. The PCI express hard IP is similar to that in the Arria® II GX and Stratix® IV GX which have successfully passed PCI SIG compliance testing.
