摘　　要：文章给出了一种基于双端口RAM技术的高速数据采集系统的设计。采用将高速双端口RAM映射为主机内存并构造成环状缓冲区的方法,实现了高速ADC数据流实时采集与主机处理的并行操作。This paper presents a design for high-speed data acquisition system based on double-port RAM. It maps the high-speed double-port RAM to the internal storage of host computer,and makes the double-port RAM become ring buffer. It realizes the parallel operation between the real-time acquisition of high-speed ADC data stream and the processing of the host computer.
