PDM-to-PCM Conversion with AMBA Interface
The AR36T01 is a soft macro low-power digital microphone interface modulator IP. The IP converts stereo/mono 1-bit pulse-density modulated (PDM) bit stream data from external digital microphones into 16-22bit pulse-code modulated (PCM) data for base-band processing. It supports AHB master interface with DMA/FIFO for data transfer to the SoC system.
The IP is portable to any logic process node for silicon realization. It is now silicon-proven in TSMC logic process.
