Looking for an FPGA with cache for BTC and Litecoin Mining - any ideas?

[.m.]

Hi, what do you think about this one ?
Virtex-7 2000T: Designed with ASIC Prototyping and Emulation in Mind - FPGA enabled by Stacked Silicon Interconnect (SSI) technology delivers 2 million logic cells, 6.8 billion transistors in 28 nm design.
Around 20W @ 100 MHz  (3600 8 bit processing elements consumed 85% chip capacity providing 180 000 MIPS)

oops - do they really cost 5000 USD each ?

LaSeek has been running simulations like crazy, they come out fast, but after synthesis they run very slow so far.

Do you have a link? I could not find much information

Proprietary design, they're not talking about it a lot.  You can try them at #litecoin-dev on freenode if you like.

I wonder if the up/down ports on the cairns more 1 fpga could be used to interface with some sort of memory.
