OCTEON™ CN30XX Single Core MIPS64 Based Embedded Processors
The OCTEON CN30XX family of MIPS64 processors targets intelligent broadband networking, control plane, storage, and wireless applications in next-generation equipment from 100 Mbps to 1Gbps. This family consists of four software-compatible processors, with a cnMIPS64 core and integrated next-generation I/Os. including Fast Ethernet, Gigabit Ethernet, TDM/PCM, and USB 2.0, along with the most advanced security, packet processing, and QoS features. CN30XX processors are the industry’s first products to deliver the performance of 64-bit computing and integrated L2 cache at sub-$20 price points. Supported by industry-standard software toolchains and operating systems, the CN30XX is ideal for 802.11a/b/g/n, VDSL2, PON, triple-play, UTM, SOHO/SMB NAS, and VoIP applications.

The cnMIPS64 core is Cavium Networks’ custom implementation of the MIPS64 release 2 instruction set, developed from the ground up for the highest networking and services performance with very low power consumption. Security hardware acceleration in the CN30XX implements the latest set of algorithms, including AES-GCM and SHA-2 (up to SHA-512) to enable future-proof designs. The OCTEON processors also integrate essential and unique hardware acceleration for intelligent networking, including TCP, packet processing, and QoS, delivering the industry’s best performance.
