Please consult the board-support guide or contact us for specific platform features supported.

The Ocelot-C is a low-power, CompactPCI form factor single-board MIPS computer that is designed for high performance applications.

The board supports the PMC-Sierra RM7900 MIPS RISC processor. The board has two Gigabit Ethernet (copper) ports implementing PICMG 2.16, as well as two Ultra160 SCSI interfaces (Ultra320 optional), two serial ports, and a standard PMC slot.

The Ocelot-C autosenses and operates as a CompactPCI system slot or non-system slot. It occupies a single slot in a standard CompactPCI chassis and is hot swappable.
