In this memo we investigate the applicability of NVIDIA Graphics Processing Units (GPUs) for SKA1-Low station and Central Signal Processing (CSP)-level processing. Station-level processing primarily involves generating a single station beam which will then be correlated with other beams in CSP. Fine channelisation can be performed either at the station of CSP-level, while coarse channelisation is assumed to be performed on FPGA-based Tile Processors, together with A\/D conversion, equilisation and other processes. Rough estimates for number of GPUs required and power requirements will also be provided.<\/p>\n","protected":false},"excerpt":{"rendered":"
