AMD, Xilinx and Celoxica announced they are working together to bring the FPGAs and related environments to Opteron based systems. The press release by itself isn't all that exciting.
What is a bit more worthy of notice is that the accelerators are here a lot earlier than most were thinking.. Notice the wording, they use phrases like "a tightly coupled co-processor expansion capability" and "Virtex-4 FPGAs as a co-processor". This is no normal product announcement, it is a shot across the bows, and there will be a lot more to follow. µ
