Data amounts of massive parallel receiver arrays as well as
latency requirements of real-time applications such as interventional MRI,
navigators etc. prompt for high-speed data preprocessing. First steps in the
reconstruction such as noise pre-whitening or channel combinations and
compressions can be efficiently performed on FPGAs. Here we present a flexible
system and software architecture for such tasks and demonstrate its capability
performing real-time coil compression directly in the spectrometer.
