gr4eme Question

Does the latest generation of DSP cores accept a DSD signal? im working on an active speaker and the source is a streaming module which has DSD outputs as well as I2S. I know the DACs i olson to use will work with DSD but im a little confused as to signal routing in the DSP core

I figured it wasn't going to be straight forward, i think i will just ignore the DSD side, thanks for the reply Ken.M

A disadvantage of DSD is that it is very difficult to perform DSP operations on the stream since it is not comprised of a stream of numbers in the traditional sense. You would need to decimate the stream before using conventional processing algorithms on this or any other processor.
