Xilinx Pioneers Uncertain Future for Chip Stacking

Xilinx Pioneers Uncertain Future for Chip Stacking
Xilinx has rolled out one of the first working commercial chips to use so-called 2.5-D stacking. The Virtex-7 2000T fired up an estimated 1.7 million logic units—about 85 percent of its silicon real estate—turning on 3,600 embedded 100-MHz PicoBlaze processors. They delivered an estimated 180,000 Mips while consuming just 19 W. "This is really packaging's turn to shine in the electronics industry, and we see it as a significant inflection point," says Liam Madden (shown), corporate vice president of FPGA development and silicon technology at Xilinx.
