摘要
设计了基于FPGA与ARM芯片的数据采集系统,FPGA负责控制A/D转换器,保证了采样精度与处理速度,ARM负责逻辑控制及与上位机交互的实现,并将采集到的数据通过USB高速上传至主机进行实时处理。对模拟数据采集的测试结果达到了较高的采样精度和速度,验证了整个系统的高速性和可行性。
FPGA and ARM chip-based data acquisition system was designed,in which,FPGA controls A/D converter to ensure a sampling accuracy and data processing speed,and ARM answers for logic control and data transmission to host through USB.The testing results prove higher sampling accuracy and data processing speed of this system.
