Abstract :
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, ARM 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.
