FPGA State of the Art document

I am wondering how old this document is? The paper claims to talk about 
the state of the art of FPGAs. However, it does not mention PICe 3.0 at 
all.

It talks about FPGAS that attach directly to the CPU socket or to the 
DIMM slot on the motherboard (see the last section for the DIMM slot 
attachment).

It does not talk about PCIe 3.0 . This make me think the paper was 
written before that that standard arrived.

The document in question can be found here.

Any help appreaciated.

Thanks in advance.

Respectfully,

Right under the abstract:

Please excuse. You are right. I found this site at the last minute when 
typing this message. The document that I originally printed out had no 
date on it.

This one does. Duh.

Thanks!

But stilll there is little mention of PCIe and a lot about FPGAs 
plugging into motherboards and into DIMM slots. It seems to me to be 
unecessary, if you have PCIe 3.0.

Any thoughts.

Respectfully,

This paper is not about the state of the art, it is about promoting FSB 
solutions.

For example they are comparing Memory Latencies with old PCI latencies, 
at a time when PCI was already in the prozess to be replaced with PCI 
Express. They also never talked about transfer rates, only boosting 
about "zero copy architecture".

2009 PCIe 3.0 was still in specificaton phase, only now you can get FPGA 
with hardcore support for it.
