Abstract

The PANDA (antiProton ANnihilation in Darmstadt) experiment at the new Facility for Antiproton and Ion Research (FAIR) will study interactions between protons and antiprotons in the momentum range 1.5-15 GeV/c. The physics program is very demanding and requires an efficient and flexible triggering system that can handle a data rate in the range 40 to 200 GB/s due to an interaction rate of over 10 MHz. A Serial-Peripheral-Interface firmware was fully developed and implemented in VHDL to interface clocks on-board the digital processing unit and the connected ADC/DAC modules. Running operation was tested successfully. Digital least mean square (LMS) adaptive filters were designed and implemented for real-time filtering in data acquisition at work frequencies higher than 100 MHz to cope the foreseen high rate of PANDA experiment.
