Interlaken is the name of a very picturesque town in Switzerland (pictured), but it’s also the name of the next communications protocol that will be driving a cloud near you! Maybe the fact that Interlaken, the town, sits between two huge lakes in the Alps is what inspired the name of the protocol. Think of the lakes as huge pools of data that needs to move from one lake to another. You get the idea.

Chip-to-chip bandwidth is one of the major bottlenecks in cloud computing as the amount of data that needs to be moved around increases incessantly. Cisco and Cortina Systems recognized the need in 2006 and announced the protocol.  The two companies joined with Silicon Logic Engineering (now part of Open-Silicon) in 2007, and put out an Interlaken Technology White Paper.

The whitepaper summarizes the protocol, “Interlaken is an interconnect protocol optimized for highbandwidthand reliable packet transfers. It uses bundles of serial links to create a logical connection between components with multiple channels, backpressure capability, and data-integrity protection to boost the performance of communications equipment.”

So, if you were to design and verify an Interlaken core on your next chip integration.  Where would you get your IP core, and where would you get your Verification IP (VIP)? After looking around, this is what we found.

Interlaken Controller IP Core
Open-Silicon’s Interlaken IP is a scalable, high-speed chip-to-chip interface protocol that builds on the channelization and per-channel flow control features of SPI4.2, while reducing the number of chip I/O pins by using high-speed SerDes technology, similar to XAUI…more
