| 摘 要： | 本文设计了一种基于FPGA的数据遗弃式双口RAM,并介绍了其在高速数据采样中的应用。这种双口RAM有存储量不大、数据存储快等优点,更重要的是其存储的数据始终是系统最新时间片的数据。然后结合AD转换芯片AD976A构建一种高速数据采样系统,实现系统的快速采样。

| Abstract: | This article designs a kind of data abandoned dual-port RAM based on FPGA,and introduces its application in data sampling.The dual-port RAM has some merits,such as memory not large,data saving faster and so on,and more important is that the data its memory always is data of the latest time slice.Then it combine with AD976,which is a piece of 16-bit A/D converter,to construct a kind of high-speed data sampling system that to carry out faster data sampling. |
