A method of processing ultrasound signals received from a plurality of data channels each associated with a transducer element. A sorted delay data table having sorted delay data is generated that includes a channel identifier, a fractional delay value, and integer delay value. The sorted delay data table clusters together channel groups including a first channel group having data channels with the first fractional delay value and a second channel group with data channels with the second fractional delay value. Control signals are generated based on the sorted delay data that implements data path combining by directing channel data from the first channel group for processing by a first interpolation filter that provides the first fractional delay value and channel data associated with the second channel group for processing by a second interpolation filter that provides the second fractional delay value. Summing signals output by the first and second interpolation filter forms the ultrasound beamformed signal.
