OCTEON® II CN66XX Processors

OCTEON® II CN66XX Multi-Core MIPS64 Processors


The OCTEON® II CN66XX family of Multi-Core MIPS64 Internet Application Processors targets high-performance, high-volume applications in enterprise routers, switches, control plane applications, appliances, 3G/4G basestations, and intelligent storage and server adapters. The family includes four software and pin-compatible processors, with six to ten cnMIPS64 v2 cores at up to 1.5GHz speed on a massively integrated SoC that includes the latest SERDES-based I/O's including PCIe Gen2, XAUI, and sRIO, along with Cavium's most advanced third-generation application hardware acceleration. CN66XX processors deliver over 15Gbps application performance.

The CN66XX provides high performance integration for next generation 3G/4G/LTE wireless base station platforms, providing up to 15GHz of compute with a large 2MB L2 cache, DDR3 memory controller, security acceleration for SNOW 3G and KASUMI, TCP/IP packet processing acceleration, and QoS. PowerOptimizer™ technology limits maximum power from 9 to 20 watts from low-end to high-end.

Support for dual 10XAUI ports along with RAID 5/6 and De-dup, combined with 15GHz of compute in a constrained power envelope, provide for high performance storage and server adapters, and enterprise class NAS/iSCSI appliances. Additional acceleration for HFA pattern matching & Compression, along with the richest set of encryption/decryption support, enables highly integrated services switches, routers, and appliances, including load balancer and WAN optimization. Supported by industry-standard software tool chains and operating systems, the CN66XX is both foot print and software compatible with CN63xx enabling customers a seamless migration for 2x performance enhancement.
