Core1990 : Royalty-free Interlaken Protocol
Core1990 is a point-to-point communication protocol using the royalty-free Interlaken protocol as its foundation.
It is designed by engineers and students of the Electronics Department of Nikhef (Amsterdam, The Netherlands) with large experiments at CERN (e.g. ATLAS) in mind.
The development of Core1990 was intended to explore and publish an open source protocol providing high throughput with a small percentage of overhead.
Certain features like flow control and error detection will be included.
The Interlaken protocol
Core1990 is developed according to the Interlaken Protocol Definition revision 1.2 which was published on October 7, 2008.
Here are some pointers to the official Interlaken alliance:

This is the current status of the project:
* Data is packed into bursts and metaframes and is unpacked by the receiver
* CRC-24/32 are generated and checked
* Data is encoded/decoded (including scrambling)
* Overall the interface including transceiver works in simulation but still needs some work
* Hardware implementation targets Xilinx devices
Last update June 2018
* Hardware implementation for Altera (Intel PSG) devices
* Support other FPGA platforms
