Cavium Networks Introduces Industry's First SPI Bridge Processor Family for Enterprise and Service Provider Equipment

Cavium Networks golden gate family of SPI bridge processors delivers intelligent connectivity between devices with SPI3, SPI4.2 and PCI/PCI-X interfaces

Santa Clara, CA, March 8, 2004 -- Cavium Networks , the cost and performance leader in security processing today introduced the GOLDENGATE SPI Bridge Processor family, the first family of Bridge Processors in the industry designed to provide bridging between devices with SPI3, SPI4.2 and PCI/PCI-X interfaces. Cavium Networks Bridge Processors offer significantly richer functionality at line-rates, faster time-to-market and consume lower power compared to FPGA-based alternatives. Each device is available in transparent and intelligent options. Cavium Networks intelligent bridge processors offer rich packet-manipulation capabilities in addition to interface bridging. The GOLDENGATE SPI Bridge Processor family interconnects devices with disparate interfaces in a wide range of multi-gigabit networking equipment such as routers, switches, DSLAMs, wireless infrastructure equipment, web-servers, server load balancers, firewalls, SANs, and VPN gateways.

GOLDENGATE SPI Bridge Processors Increases Connectivity between Devices SPI-3, SPI4.2 and PCI-X are popular interfaces for a wide range of communication silicon including control-plane processors, network processors, security processors, traffic managers, switch fabrics, x86 chip-sets, media access controllers (MACs) and framers. System designers that want to use silicon components with these disparate interfaces have previously had to develop FPGA-based connectivity solutions themselves. Cavium Networks GOLDENGATE SPI Bridge Processor family is designed to provide a fast, cost effective, feature-rich, off-the-shelf and intelligent solution to bridge between devices with SPI-3, SPI4.2, PCI and PCI-X interfaces.

" We chose Cavium Networks GOLDENGATE SPI Bridge processor chip because it enabled us fast time to market for Astute Networks' SuperHBAT Accelerators for multi-gigabit iSCSI and TCP offload," said Roger Moyers, COO of Astute Networks.  "This allowed us to easily bridge Astute's PericlesT Intelligent Protocol Processor with its SPI-4 interface to both a multi-port gigabit Ethernet MAC and the industry-standard PCI-X interface.  Cavium Networks offered the only off-the-shelf component which met our requirements ."

Broad product line for enterprise and service-provider equipment The GOLDENGATE SPI Bridge Processor family has five members to target a wide range of interface combinations, allowing OEMs to connect various devices in a variety of enterprise and service provider equipment. All five parts are available in "transparent" and "intelligent" versions and include large on-chip buffer that eliminates the need for external memory. Intelligent versions of the bridge processors allow for packet processing, such as header manipulation and packet integrity checks to be performed at line-rates. These tasks reduce the workload on the CPU/NPU allowing it to handle other compute intensive L3-L7 tasks. The new GOLDENGATE Bridge Processor CN2B100 provides SPI-3 to PCI/PCI-X connectivity, the CN2B200 part provides SPI-4.2 to PCI/PCI-X connectivity, CN2B300 part connects a SPI-3 interface to a SPI-4.2 interface, CN2B400 part connects a SPI-3 interface to a SPI-4.2 interface and a PCI/PCI-X interface, and the CN2B500 connects 2 SPI-4.2 interfaces to a PCI/PCI-X interface. The PCI bus on the various parts supports version 2.2 and the PCI-X bus supports version 1.0. The power dissipation varies from 4 - 8 watts depending on the part. All parts come in a 1096 HSBGA package.

Acknowledging the ubiquitous requirement for bridging, the company has chosen to separate the bridging function out as a standalone, new product family," said Sanjay Iyer, Senior Analyst at the Linley Group. "Based on their derivation from Cavium Networks proven technology, these lower-cost replacements for the FPGAs traditionally used for bridging can also perform transformations on streaming data, increasing their utility and adaptability for networking applications".

"Cavium Networks design team has developed industry-leading competence in high speed CPU and IO design. Our award-winning NITROX security product family was the first product family built on this competence. The GOLDENGATE SPI Bridge Processor family provides us with an opportunity to leverage our developed intellectual property into another product area of the communication market segment", said Syed Ali, President and CEO of Cavium Networks. "With a wide range of interfaces and its unique intelligence features, GOLDENGATE SPI Bridge Processor family dramatically reduces customer's time and cost of implementing bridging in the Enterprise and Service Provider equipment markets."

Complete Solution
Cavium Networks complete solution includes chips, evaluation boards (reference hardware designs), and drivers. The GOLDENGATE SPI Bridge Processor evaluation/development kit is supported by drivers and chip configuration utilities. The intelligent bridges include microcode as well. With this software and hardware reference, customers can quickly integrate GOLDENGATE SPI Bridge Processors with minimal engineering effort.

Product Pricing and Availability
Samples for all five GOLDENGATE SPI Bridge Processor products are available today, with production in Q2 '04. GOLDENGATE SPI Bridge Processor products range in price from $100 to $175 in 10K quantities.
