| OCTEON™ CN38XX/CN36XX Multi-Core MIPS64 Based SoC Processors |
| The OCTEON CN38XX and CN36XX family of Multi-core MIPS64 processors targets intelligent, multi-gigabit networking, control plane, storage, and wireless applications in next-generation equipment. The family includes fifteen software-compatible processors, with four to sixteen cnMIPS64 cores on a single chip that integrate next-generation networking I/Os along with the most advanced security and application hardware acceleration.
The cnMIPS64 core is the industry’s first 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 CN38XX/CN36XX 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 compression/decompression, TCP, and pattern matching, delivering the industry’s best performance. Supported by an industry-standard software toolchain and operating systems, the CN38XX and CN36XX offer a 3x+ performance, power, and real estate value proposition over alternatives.
For new designs, we recommend using the OCTEON II family of Multi-Core MIPS64 Processors.
