RapidIO

The RapidIO architecture is a high-performance packet-switched, interconnect technology. RapidIO supports messaging, read/write and cache coherency semantics. RapidIO fabrics guarantee in-order packet delivery, enabling power- and area- efficient protocol implementation in hardware. Based on industry-standard electrical specifications such as those for Ethernet, RapidIO can be used as a chip-to-chip, board-to-board, and chassis-to-chassis interconnect. The protocol is marketed as: RapidIO - the unified fabric for Performance Critical Computing, and is used in many applications such as Data Center & HPC, Communications Infrastructure, Industrial Automation and Military & Aerospace that are constrained by at least one of size, weight, and power (SWaP).
