Today’s hearing aids use highly-specialized signal processing algorithms to process input from a multi-microphone array, which requires an efficient controller along with specialized signal-processing units for real-time execution. MIPS’ DesignWare ARC processors and ASIP tools provide the functionality and performance needed while maintaining low power consumption for these battery operated hearing aids.
