[LAD] entailments of probabilistic processing chip for DSP and audio processing?

[Charles Henry]

hmmm... interesting

The discussion is mostly about improvements to existing algorithms
such as error checking and correction and encryption.  So, it leads me
to ask if there are any such problems in the DSP field that could be
addressed with it?  Please, please don't let it be DRM :P

Seems like markov processes and Bayesian modelling problems could be
implemented (although I'd really like to see the math btw input/output
on the gates before I conjecture--I'll do so anyway.)  Speech
analysis/recognition could be made less costly.  Maybe there could
even be a small speech co-processor for mobile devices.

or how about source separation and the ever elusive automatic
transcription problem?
