Comparison helps you see quickly which core carries less license, review, and integration risk.
Raw PDM RX core на Verilog-2001 для MEMS microphones: генерирует PDM clock, сэмплирует 1-битный поток и выдаёт valid/ready stream. Не выполняет PDM-to-PCM decimation.
Source is available, but commercial use may require a separate license.
The core does not include a decimator/CIC/FIR pipeline.
