Abstract

In recent years, although design systems using high-level synthesis are becoming practicable, yet they are not powerful enough to design the digital signal processing (DSP) applications which are needed in real-time processing. In this paper, we introduce the system synthesis based on the assumption that a behavioral description is mapped to an architecture for distributed processing, and design several DSP algorithms which include the Forward algorithm for HMM (Hidden Markov Model) speech recognition. We also evaluate execution time and hardware resources of those applications, and indicate that the new design methodology is suitable for those DSP algorithms
