Designed for the PYNQ-Z2 FPGA board
This repo containts the complete hardware design for a scalable PDM-to-PCM audio conversion pipeline. It supports:
- Conversion of 32bit/96kHz digital audio
- Scalable to an arbitrary number of microphone devices/channels
- PL to PS (hardware to software) data offloading through the DMA engine
- Sound source amplification with saturation and clipping
