ARCHITECTURES FOR SPEECH PROCESSING

After a short investigation about the various solutions for specific integration of complex digital processing application, for specific integration of complex digital processing applications, circuit and standard microprocessor core proliferation. This approach is based upon the use of CAD tools easily available and provide a relative independence of design methods. The price to pay is a formalisation of the specification, the use or development of a parameterizable compiler, but the expected benefits lie in shortening the design time and improving security. The first example treated is the GSM 13 kbit/s vocoder for pan-European cellular radiotelephone.
