  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.
