Fujitsu Microelectronics America Delivers Trio of ASICs to Innovative Start-Up Greenfield Networks

Built using Fujitsu's 0.11-micron process technology, ASIC includes the first network processor streaming interface at 1.3 gigabit/second

Sunnyvale, CA, May 10, 2004 — Fujitsu Microelectronics America, Inc. (FMA) has delivered three high-performance ASICs to Greenfield Networks, Inc., the emerging leader in world-class Ethernet switch silicon technology. Greenfield Networks PacketryTM family of Ethernet switching products provides advanced packet processing and traffic management silicon solutions for a broad range of networking applications in enterprise and metro markets.

Fujitsu's ASICs, which are designed for network traffic management and packet processing, incorporate the industry's first SPI-4P2 Network Processor Streaming Interface running at 1.3 Gigabits/second. ASICs range in size from a few million to over ten million gates, including memory operating at core frequency of 250MHz.

The first ASIC in the Fujitsu series provides 32Gbps of interface bandwidth as well as over 75Gbps of memory bandwidth. This memory bandwidth has enabled Greenfield Networks to support up to 256MB of external buffer memory. The large buffer memory is critical for high-performance networking applications. The second device supports both the RGMII interfaces to Gigabit PHYs and a SPI4.2 interface operating up to 622 MHz DDR. This flexibility enables high-density Gigabit Ethernet connectivity as well as interfaces to 10 Gigabit Ethernet or OC-48/192. The third ASIC is a highly integrated solution that provides 10Gbps of interface bandwidth. All of the ASICs were manufactured using Fujitsu's advanced 0.11-micron process technology.

These ASICs incorporate a complete set of I/Os, including 66MHz PCI, 250MHz HSTL with Double Date Rate (DDR) memory interface, and Low Voltage-TTL along with the 1.3Gbps SPI-4P2 Network Processing Streaming Interface (NPSI), which represents the first implementation of this new standard. The NPSI supports transfer of network traffic between a pair of network processor devices. It is used primarily for passing packets between an NP and an adjacent physical layer, co-processor, or switch fabric.

Fujitsu Microelectronics delivered these complex devices very efficiently, moving from final netlist to tape-out in just 20 weeks, according to Keith Horn, FMA's vice president of marketing. The ASICs are implemented in three initial members of the Packetry family, the G525 Packet Engine, the G750 Shared Memory Fabric, and the G120 Intelligent Multiplexer.

"These new ASICs are designed for packet-processing and traffic-management applications in new generations of network systems," said Horn. "These applications have become key elements in next-generation IP-based networks. We are very pleased to be working closely with Greenfield Networks, which is emerging as an exciting and innovative leader in Ethernet switch technology."

"Fujitsu Microelectronics delivered excellent ASIC products to us in a timely manner. Our efficient collaboration was integral to our Packetry product introduction," said Gary Smerdon, president and CEO of Greenfield Networks. "Fujitsu helped us meet the demand for full IPv6 support, including routing, QoS, access control lists, and IPv4 to IPv6 transition mechanisms, all essential capabilities for high-performance Ethernet systems."

Greenfield Networks' Packetry is the first merchant silicon to provide full IPv6 support for unicast/multicast routing. The Packetry family enables new metro edge deployments, supporting extensive service-provider features including MPLS switching, stacked VLANs, Layer 2 VPN (martini encapsulation and VPLS), Layer 3 VPN (RFC 2547bis) and IP tunneling. Packetry's advanced functions for wirespeed multi-field classification, traffic policing/shaping, guaranteed bandwidth, and WRED enable voice over IP, streaming media, and other converged applications that require flow-based priority and bandwidth distribution across the network.
