Abstract
Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.
