'''OCTEON''' was a family of {{arch|64}} [[multi-core]] [[MIPS]] microprocessors designed by [[Cavium]]. These processors are primarily marketed towards makers of network infrastructure (commercial, enterprise, and data center switches, routers, etc..). Cavium offers OCTEON processors with anywhere from [[single-cores]] to [[hexadeca-cores]].

== 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, {{cavium|cnMIPS|l=arch}}, announced the same day. The cnMIPS design is a fully compliant {{mips|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|cavium/microarchitectures/cnmips|l1=cnMIPS µarch}}
The cnMIPS microarchitecture is a [[fully-custom]] design implementing the {{mips|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]]).

== Members ==

=== CN3000 Series ===
The CN3000 series is entry-level processors containing just one cnMIPS core. Depending on the option, these processors either have an array of security-related hardware accelerators (e.g. [[AES]], [[TRNG]]) or various communication accelerators (e.g. hardware packet I/O processing). Additionally, all models have 1-3 [[RGMII]] interfaces, [[Conventional PCI]] interface, and USB 2.0. The 3010 models also have an TDM/PCM interface for direct VoIP communication.

=== CN3100 Series ===
The CN3100 series includes both 110 and 120 models. Apart from their core count, they have an identical feature set which includes (depending on the version of the model chosen) an array of hardware accelerators for packet I/O processing, [[encryption]], [[TCP]], [[QoS]], compression/decompression, and [[RegEx]]. Additionally, these models support a faster [[PCI-X]] bus operating up to 100 MHz, gigabit Ethernet ([[GMII]]), and up to DDR2-667 ECC memory.

=== CN3600 Series ===
The CN3600 series are [[quad-core]] microprocessors. The CN3600 series is identical in terms of features the CN3800 series with just half the cache.
