Low-power architectural trade-offs in a VLSI implementation of an adaptive hearing aid algorithm
- Conference Paper
This paper analyzes the power-area trade-off of functionally equivalent architectural implementations of a speech enhancement algorithm for hearing aids. Gate-level simulations and measurements show that an optimum degree of resource sharing (0.60mW in a 0.25μm CMOS process) is more energy-efficient than both the fully time-multiplexed (1.42mW) and the isomorphic architecture (1.54mW), without overly large area overhead (0.77mm2 against 0.43mm2 and 4.31mm2, respectively).
