Massively Parallel Processor Array for Mid-/Back-end Ultrasound Signal Processing

Nominated for Best Student Paper.

Abstract:

Ultrasound remains a popular imaging modality due to its
mobility and cost-effectiveness. As general purpose computing and DSPs
are entering an era of multi-core architectures, the potential for parallel
performance gains are significant when used properly. This work explores
the possibility of using a massively parallel processor array to meet 
realtime throughputs for mid-/back-end ultrasound processing. A many-core
array of simple DSP cores, shared memories, and an FFT processor is
shown to dissipate 87.79 mW for B-mode, 33.20 mW for color flow, and
29.24 mW for spectral doppler, while achieving a frame rate of 37.6 fps
for B-mode and 12.5 fps for color flow.
