[alsa-devel] New Audio Driver Design

Hello, I am to write an ALSA driver for my SOC which has a dedicated DSP subsystem which can be loaded with decoder instructions and parameteres, and then we load it with encoded data. The dsp then decodes the data and sends it to the PCM controller.

Could someone please refer me to some similar driver/codec which already does that? If not, how should i design the driver? :- Should I load the encoder inst/params using firmware API? Then, which API should I use to submit encoded data to the DSP?

Any pointers please?

Thanks.
