MANHASSET, NY -- Xilinx Inc. has begun initial shipments of the Virtex-7 H580T FPGA, a single-chip solution for addressing key Nx100G and 400G line card applications and functions.
The part uses its stacked silicon interconnect technology in the 3-D heterogeneous FPGA which is built on TSMC’s 28nm process. The H580T has eight 28 Gbps and forty-eight 13.1 Gbps transceivers. Xilinx claims other FPGAs are able to integrate only a fourth of the number of 28 Gbps channels.
“Xilinx has clearly hit an industry milestone with this device because it allows makers of networking systems to easily overcome the challenges they face to enable more bandwidth,” said Chris Bergey, Vice President of Marketing at silicon photonics leader Luxtera Inc., a maker of 4x28 Gbps single chip silicon photonic transceivers, in a statement.
Effectively upgrading networks to handle exponential growth in data usage requires power and port density improvements in optical modules while reducing cost per bit. Driven by the migration to CFP2 and, in the future, CFP4 optical modules, Virtex-7 HT devices enable that capability for communication equipment vendors designing Nx100G and 400G line cards.
“Competing ASSP-based solutions will comprise five devices, will remain unavailable for more than a year, will consume at least 40 percent additional power and will cost 50 percent more,” claimed Mark Gustlin, System Architect for Wired Communications at Xilinx.
David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
