With Xilinx's (xilinx.com) announcement of the first shipments of its Virtex-7 2000T Field Programmable Gate Array (FPGA), the era of 2.5D has begun.Xilinx reports that the 2000T is the world's highest-capacity FPGA using 6.8 billion transistors, providing customers access to an unprecedented 2 million logic cells, equivalent to 20 million ASIC gates for system integration, ASIC replacement, and ASIC prototyping and emulation.Co-design with packaging technology has created a new FPGA that reduces system cost and increases performance with lower power. By not having to drive off-chip 1/ Os across PCB traces to adjacent FPGAs, designers for high-performance applications that have previously used multiple FPGAs in their systems will be able to benefit from the high-bandwidth, low-latency, power-efficient interconnect between the FPGA die.The key to the performance gains is the silicon interposer or what Xilinx calls its "Stacked Silicon Interconnect" technology.
