基于ARM+DSP架构的可控震源扫描信号发生器设计

The design of vibrator sweep signal generator based on ARM&DSP structure

针对可控震源中扫描信号发生器的研究,本文提出了一种基于ARM+DSP架构的设计思想,并详细阐述了以ARM为主处理器完成人机界面、通信和控制等任务,以DSP作为协处理器完成各种算法的实现过程。该系统在实时产生信号后,可通过高速采集对信号进行质量的评价并及时调整信号参数,达到最佳信号品质的输出。

This paper describes a new design of sweep signal generator which is based on ARM^DSP. The paper not only introduces the implementation process in detail based on the ARM as the main processor for completing the task of interface, communication and controlling, but also introduces the implementation process based on the DSP as the co- processor. Through high-speed acquisition after generating in real-time, the signal quality can be evaluated then the signal parameters can be adjusted in time to achieve the best signal quality output.
