OCTEON was a family of 64-bit multi-core MIPS microprocessors designed by Cavium for networking devices.

Overview

The original OCTEON family of network-oriented microprocessors were announced in September of 2004. These chips are based on Cavium's newly announced microarchitecture, cnMIPS, announced the same day. The cnMIPS design is a fully compliant MIPS64 revision 2 implementation. OCTEON chips are found in many enterprise an data center network servers, routers, and switches as well as various high-end residential routers.

Architecture

Main article: cnMIPS µarch

The cnMIPS microarchitecture is a fully-custom design implementing the MIPS64 revision 2 ISA on TSMC's 130 nm process. Due to the specific nature of the applicatons running, an FPU was omitted. Instead, Cavium opted to incorporate a wide array of hardware accelerators for network applications (L3 to L7) including support for compression/decompression algorithms (e.g.GZIP), and security/crypto algorithms (e.g. DES, AES, MD5, and SHA1).
