Integrated circuits for auditory speech processing

Nebel, Wolfgang and Brucke, Matthias and Çakir, Mustafa
Deriving an implementable application specific integrated circuit (ASIC) from the functional specification of an auditory speech processing algorithm requires several refinement steps. These include design decisions on the data representation, the detailed scheduling of the operations and the resources allocated. We give an overview of these steps and illustrate them with an ex-ample, the ASIC implementing an auditory perception model. We demonstrate the optimization potential of custom integration and the need for objective quality measures to assess the impact of design decisions. The paper concludes with a summary of the results for the example circuit.
