In today's nuclear and high-energy physics experiments the background-induced occupancy of the detector channels can be quite high; therefore it is important to have sophisticated trigger subsystems which process the data in real-time to generate trigger objects for the global trigger decision. In this work we present a FPGA based low-latency trigger processor for the COMPASS-II experiment.

TIGER is a high-performance trigger processor that was developed to fit perfectly in the GANDALF framework and extend its versatility. It is designed as a VXS module and is allocated to the central VXS switch slot, which has a direct link from every payload slot. The synchronous transfer protocol was optimized for low latencies and offers a bandwidth of up to 8 Gbit/s per link. The centerpiece of the board is a Xilinx Virtex-6 SX315T FPGA, offering vast programmable logic, embedded memory and DSP resources. It is accompanied by DDR3 memory, a COM Express CPU and a MXM GPU. Besides the VXS backplane ports, the board features two SFP+ transceivers, 32 LVDS inputs and 32 LVDS outputs to interface with the global trigger system and a Gigabit Ethernet port for configuration and monitoring.
