The SpaceFibre Single-Lane Interface IP Core provides a complete SpaceFibre interface which can provide data rates up to 3.125 Gbit/s in the RTG4 and 6.25 Gbit/s in the RT PolarFire after TMR (can work much faster without TMR). It is an efficient design that uses a small portion of a host FPGA, less than 2% of an RTG4 and around 1% of an RT PolarFire (including TMR). This leaves most of the FPGA for the user application.
