Description
The Station Digital Processor (SDP) in a LOFAR2 station consist of a digital beamformer and a subband correlator. This year we have added a transient buffer function that can store 4 seconds of ADC data for all antennas in DDR4 memory, and that will be used to investigate the behavior of lighting. The SDP gateware runs on FPGAs of the UniBoard2. The SDP gateware that we use for LOFAR2 builds upon HDL libraries that were also used and extended during previous projects that we did in the last 20 years. In this presentation I will highlight some of the HDL libraries and explain how we maintain and improve the quality of our code.
