| Abstract: | A data-acquisition system was proposed based on the DSP and the dual-port RAM, and the scheme of hardware wiring was brought forward. Whether the conflict takes place when the dual-RAM was accessed by ADC and DSP simultaneously was the crucial problem of the design of the system. The hardware arbitration was discussed particularly and the method of the design of software was given. The configuration of system is reasonable and it is useful in practice. |
