Methodology to design reconfigurable architecture for acoustic algorithms

This paper proposes a novel approach to implement reconfigurable architecture dedicated to acoustic algorithms. To explore different reconfigurable architecture suitable for acoustic algorithms, a methodology called virtual embedded block has been applied to identify suitable building blocks which can be a good candidate to embed into existing reconfigurable devices to increase the performance of the devices when acoustic computations are involved. Two acoustic algorithms, namely echo cancellation and beamforming, have been studied to demonstrate how this methodology applies to real life scenario. This methodology offers a rapid way to estimate how the embedded blocks in reconfigurable devices affect the performance of acoustic algorithms.
