采用FPGA的双通道500 MHz的数据采集卡

Two channels data acquire card up to 500 MHz using FPGA

对于高速数据采集系统设计而言,除了器件的处理速度之外,如何协调地解决总线控制逻辑、如何进行高速存储以及如何方便地与主机进行交换数据等一直是高速数据采集系统设计的难题。针对这些问题,本文介绍了一种基于FPGA实现的设计思想和方法。这种设计经过实际验证,工作稳定,能很好地达到预期要求。

For all the DAQ of high speed, how to use high speed parts of an apparatus, how to control bus logic,how to store, and how to change for data with host expediently are challenges in DAQ existing all along. In this paper, the process of dealing with high speed data with FPGA is introduced, which has been validated in practice, and it can work stably and meet the need of expectation.
