| Abstract: | In this paper, a speech collecting system which runs on TMS320C54x digital signal processor (DSP) is described. Several communication Methods between this series of DSPs and other peripheral equipments are also explored and presented here. The experimental results shows that using UART processor (ST16C550) is not only the simplest communication method, but also a feasible and effective approach. The system runs smoothly without any problems occured for two weeks which is our first test period. |
