Concurrent process structured software models for time domain harmonic scaling of speech

Concurrent process structured software can be used as a tool for studying the behavior of parallel digital signal processing systems. By modeling alternative architectures for a given application and characterizing the interactions of concurrent processes, an evaluation of relative efficiencies can be made. Presented here are models of three architectures for time domain harmonic scaling (TDHS) of speech. Their implementations and the software tools required to study their behavior are described.
