From (edited for clarity): "The Cavium Networks OCTEON family of Multi-core MIPS64 Processors is [wonderful]. These software-compatible processors, with 1 to 32 cnMIPS cores on a single chip, integrate ... networking I/Os ... and application hardware acceleration [so they're great for] intelligent networks."

MontaVista Software, on this page, list the Cavium Networks OCTEON with availability "Contact MontaVista" for their MontaVista Linux Professional Edition product. added support for the OCTEON SOC family in 2.6.29-rc2.


Cavium Networks acquired Brecis Communications' MIPS-Based Secure Communication Processor product line at Q4 2004. Through the acquisition, Cavium received Brecis' MSP2000, MSP2010 and MSP2100 processors. Cavium Networks sells these products under its NITROX SoHo brand as the CN200, CN201 and CN210 respectively. These processors include:

  • MIPS 4Km processor core (w/o MMU)
  • 16 kbytes of I-cache, 16 kbytes of D-cache, 16 kbytes of scratchpad memory
  • 32-bit SDRAM interface
  • one to three fast Ethernet interfaces
  • PCI interface
  • UARTs
  • GPIOs
  • VPN engine


  • Cavium ships a Debian root filesystem in its SDK
  • OpenWrt supports Cavium Octeon
  • Gentoo supports Cavium Octeon by providing mips64r2 root filesystems
