Design of the Different Multi-processors System Based on TFG Model

Cooperation design method based on analysis and application of TFG (task flow graphic) model is introduced for different multi-processors system used for the signal waveform scale in the both time-domain and spectrum-domain in this paper. The method is based on the TFG model of the digital signal process algorithm and implemented with multi-processors technology. The multi-processors system consists of DSP (digital signal processor), ARM (advanced RISC machine) and Nios II processors is discussed. And the whole structure of the system and the structure of each subsystem are given. Then a measurement instrument integrated with simple digital oscilloscope and spectrum analyzer using this multi-processors system is realized. Besides, the hardware architecture and software program flow chart of the real system, as well as the communication approach among the processors, are provided.
