ABSTRACT, Concurrency: Practice and Experience 1996

 This paper presents several parallel DSP (Digital Signal Processing) algorithms and their performance analysis, targeting a hybrid message-passing and shared-memory architecture that we have built here at NJIT. The current version of our system contains eight powerful TMS320C40 processors. The algorithms are implemented on our system using message-passing only, shared-memory only, and, if possible, a combination of both of these parallel processing paradigms. Comparisons show that TurboNet's robust, hybrid architecture results in significant performance gains because of the flexibility it introduces.
