Recently, emerging mobile computing requires the high integration of hearing aids into a single system-on-chip. Modern hearing aid systems include a frequency decomposer, noise reduction, feedback cancellation, auditory compensation, and intelligent adaptation. The majority of existing works concentrated on improving the performance and efficiency on a single-signal processing block or one-sided effect...
This paper presents a power-efficient computing platform for hearing aids. The proposed platform composes four heterogeneous processing elements. Each processing element includes one tiny RISC processor and several power-efficient hardwired accelerators. The hardwired accelerators integrate static floating-point and truncated multiplier to improve signal-to-noise ratio and reduce computational complexity...
