摘要
为解决高速数据采集系统中的数据缓存和传输速度瓶颈,设计并实现了一种基于光纤通道协议和DDR2 SODIMM存储的高速数据传输、存储系统。利用Stratix Ⅳ GX系列FPGA和QuartusⅡ中自带的DDR2 IP核以及高速收发器IP核,实现了PCI9056的本地接口、DDR2控制器、光纤通道协议和高速串行数据的转换发送,最终实现了数据的高速存储和传输。
To tackle the bottleneck of data-caching and the transmission speed in the high-speed data acquisition system, a new high-speed data transmit-save system is designed in this paper. Via utilizing the Stratix IV GX series FPGA, as well as the built-in DDR2 IP core and high-speed send-receive IP core of Quarturs II, the local port of PCI9056, DDR2 controller, fiber channel protocol and transformation and sending of high-speed serial data are realized. Based on it, a new high-speed data- caching and transmission system is implemented.
