Cavium Networks Launches Industry's Broadest Line of Single and Dual Core MIPS64®-based OCTEON™ Processors Targeting Intelligent Next Generation Networks

New OCTEON SoC Processors Introduce Highly Integrated, Cost Effective 64-bit Computing for Networking, Wireless, Control, and Storage Applications

MOUNTAIN VIEW, CA, January 30, 2006 – Cavium Networks, a world leader in security, network services and embedded processor solutions, today unveiled ten new highly integrated single and dual core MIPS64 processors starting at under $20 price points. The new SoC (system on chip) processors integrate a custom MIPS64 processor core with the industry’s most advanced multi-layer application acceleration and security processing hardware, along with a wide range of networking I/O options to deliver breakthrough features, price/performance and power for next generation networking, wireless, control and storage applications. The new OCTEON CN31XX and CN30XX family of processors are fully software compatible with the market leading OCTEON CN38XX family of multi-core processors. The OCTEON family now delivers industry's most scalable line of compatible MIPS64 processors from single core to sixteen cores. This enables OEMs to build equipment at a wide range of price performance points with a common software code base that results in dramatic reductions in development cost and time-to-market. The OCTEON processor family is being designed into a wide array of networking equipment, including routers, switches, unified threat management (UTM) appliances, application-aware gateways, triple-play gateways, WLAN and 3G access and aggregation devices and storage networking equipment.

Secure, Content and Application Aware Networks
Networks are evolving to deliver a flexible mix of data, voice and video content. Data rates are increasing with the deployment of technologies such as Gigabit Ethernet, GPON, VDSL2, 802.11n and 3G/4G wireless technologies. In addition, application delivery mandates the need to process intelligent Layer 3 to Layer 7 data and content at line rate. Multi-layer security including encryption, authentication, Intrusion Prevention and Anti-Virus has also become a necessity. Furthermore, multifunction integration of routing, security, wireless, VoIP and storage functionality is becoming important. Existing processors lack the horsepower to meet the demands of today’s networks. Current solutions use a GHz class processor along with several coprocessors and FPGAs that results in performance bottlenecks, unacceptably high cost and power. The new OCTEON CN31XX and CN30XX processors have been architected to address all the requirements for next generation IPv4 and IPv6 networks cost effectively. The OCTEON processors integrate extensive hardware acceleration options for Layer 3 to Layer 7 data, content and security processing. These accelerators offload the 64 bit MIPS CPU and reduce CPU clock rates required to achieve Gigabit line rates resulting in a substantial reduction in power and cost, thereby enabling widespread deployment in a scalable manner from 100 Mbps to multi-Gbps.

“Cavium Networks’ new processors include the most comprehensive set of security and application acceleration functions in any low-cost processor,” said Linley Gwennap, Principal Analyst at the Linley Group. “With these products, Cavium is unique in offering a software-compatible family scaling from a single general-purpose CPU to 16 CPUs in a single chip. This breadth will allow customers to develop standard C-based programs and leverage this software into many types of networking equipment at multiple price/performance points.”

The OCTEON CN31XX and CN30XX Family of Processors

The OCTEON CN31XX and CN30XX processors are based on the same custom cnMIPS64 CPU core as in the currently available CN38XX and CN36XX family of processors. The core has been developed from the ground up for the highest networking and services performance with very low power consumption. The cnMIPS core is the industry’s first implementation of MIPS64 Release 2 instruction set with a 5-stage, dual-issue superscalar architecture, sophisticated pre-fetching and optimized cache and memory latencies. Each processor has 1 or 2 cnMIPS cores, along with up to 256KB L2 cache and features an extensive set of I/Os including Gigabit Ethernet networking interfaces, PCI/PCI-X, DDR2, USB 2.0 with PHY, TDM/PCM for Voice applications, and other standard I/O such as GPIO, SPI, UARTs and Expansion bus. The processors vary in frequency from 300MHz to 550MHz. Maximum power consumption of the parts ranges from under 2 Watts to 7 Watts while application performance ranges from several hundred Mbps to 2Gbps.

The CN31XX and CN30XX processors are available with an extensive set of hardware acceleration options. Each processor is available in CP (Communication Processor), SCP (Secure Communication Processor) and NSP (Network Services Processor, available on CN31XX only) versions. The CP version includes hardware acceleration for Packet Processing, TCP, Queuing/Scheduling and QoS. The SCP version adds acceleration for IPsec/SSL, SRTP and WLAN security. The NSP further adds acceleration for Deep Packet Inspection and Compression /Decompression. Details of application acceleration features are:

Extensive L2-L4 hardware based packet processing and buffer management engines for IPv4 and IPv6 packets
TCP hardware acceleration includes comprehensive checks, tag-generation, checksums, timer and buffer management
Queuing/Scheduling and QoS hardware implements packet input queuing/scheduling based on diffserv, QoS/ToS, Input ports or a combination. Output packet queuing and scheduling based on fixed prioritization and or weighted fair queuing (WFQ)
Future-proof security hardware acceleration includes full offload for IPsec, SSL, SRTP and WLAN 802.11i security and support for all standard algorithms including DES/3DES, AES up to 256bit, AES-GCM, AES-XCBC, ARC4, MD5, SHA-1, SHA-2 up to SHA-512, RSA up to 4096 bit, Diffie-Hellman and a true hardware random number generator
Compression/decompression hardware acceleration implements GZIP, PKZIP and variant protocols to deliver industry’s best compression ratio at multi-gigabit throughputs
Deep Packet Inspection is enabled through 8 Pattern matching hardware acceleration engines. These engines perform stateful pattern analysis for intrusion detection, anti-virus and content based switching, routing and filtering applications
