  Design, implementation and setup of a FPGA and RocketIO based FPS(Fast Protection System) for CSNS(China Spallation Neutron Source) is introduced. This system is a compact design with high speed serial transmission techniques. RocketIOs (or MGTs) and optical transceivers are used to transmit the interlock signals, with each link to carry 16 signals. Ground loop problems are avoided since the use of fibers. Dedicated firmware is developed for the auto-working of the serial links when both fibers are plugged in under power-on state. A real-time online heart-beat function is also implemented for each interlock signal to make sure the overall safety of the system. The whole system is under installation and will be put into use soon part by part according to the progress of the civil construction and equipment installation.
