OCTEON CN38XX/CN36XX 4 to 16-Core MIPS64 Based SoCs
Product Brief
The OCTEON
®
CN38XX and CN36XX family of Multi-core MIPS64 processors targets intelligent networking,
control plane, storage, and wireless applications in next-generation equipment from 1Gbps to 10Gbps performance.
The family includes 15 di erent software-compatible parts, 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 to deliver a 3x – 5x performance, power and real-estate value proposition over alternatives.
