Methods and Apparatus for Efficient Vocoder Implementations

Techniques for implementing vocoders in parallel digital signal processors are described. A preferred approach is implemented in conjunction with the BOPS(R) Manifold Array (ManArray(TM)) processing architecture so that in an array of N parallel processing elements, N channels of voice communication...

description	Techniques for implementing vocoders in parallel digital signal processors are described. A preferred approach is implemented in conjunction with the BOPS(R) Manifold Array (ManArray(TM)) processing architecture so that in an array of N parallel processing elements, N channels of voice communication are processed in parallel. Techniques for forcing vocoder processing of one dataframe to take the same number of cycles are described. Improved throughput and lower clock rates can be achieved.
