Can Impulse C be used to develop PCIe like devices where an IP Core has to be used?

In particular can Impulse C be used with an Arria GX development kit?

[RalphBodenner]

There is currently no Platform Support Package (PSP) that supports Impulse C streams using the Altera PCIe megafunctions that come with the Arria GX kit. The PSP system, however, does allow an interface to be developed between streams and the PCIe cores.

Impulse C does support other PCIe cards and kits, and other high-speed bus interfaces such as HyperTransport.

Thanks Ralph:
What other PCIe kits are presently working with ImpulseC? I have a Xilinx ML505 and a Lattice ECP2/M kit, but the PCI like interface and design does not appear to be suited with streams. My guess is that, for my design, a dual-ported memory and register interface is required. PCIe is very much: wait for an appropriate multi-staged TLP read/write request and then respond to it very asynchronously.
