片上可编程系统在地震数据采集中的应用

Application of SoPC in seismic data acquisition system

通过灵活配置,采用包括NiosⅡ CPU软核、采集控制接口、通讯接口以及数据传输控制模块等一些外围接口,配合ADC采集芯片,组成了一个具有采集控制和传输功能的数据采集系统。通过测试和实验,达到了预期的设计要求。缩短了开发周期,提高了研发的工作效率。

With its flexible configuration which includs the NiosII CPU, acquisition and control interface, communications interface and data transmission control module and ADC chip, we achieve a data acquisition system including the acquisition and transmission function. By the tests and experiments, it achieves the desired design requirements. It shortens the development cycle, improves the efficiency; so it is a good design ideas and methods in the seismic data acquisition system.
