It is hard enough finding tutorial type information for NEON, nevermind the DSP

DSP is really faster, because it has several multiply-accumulate units cascaded with each other. This makes it very efficient in certain tasks, i.e. those stated above (filters, fourier transform, etc). CPU does not have cascading to the same extent.
