摘要
目前存储器需存储的数据量越来越大,高速数据传输系统的需求变得极为迫切;为实现海量数据的高速稳定传输,并同时具有便携性及兼容性等特征,介绍了一种以FPGA为控制核心,DDR2SDRAM为高速大容量缓存,USB3.0接口作为记录器与计算机进行数据通信接口的高速数据传输系统,通过模块硬件电路及软件协议实现了数据的高可靠性稳定传输,解决了大容量存储器和计算机之间的数据传输速度瓶颈;经长期试验证明:该接口传输速度可稳定达到150 M/s,且数据可靠无误,满足任务设计要求。
At present, the amount of data to be stored in the memory is increasing, the need of high-speed data transmission system becomes extremely urgent. To achieve highly stable transmission of large quantities of data, and also has features such as portability and compatibility, a high--speed data transmission system was introduced, which regards FPGA as a control core, DDR2 SDRAM for high-speed large-capacity cache, USB3. 0 for data communication interface between recorder and computer. By module hardware circuitry and software protocols, it has achieved highly reliable and stable transmission of data, and solved large--capacity data transfer speed bottleneck. The long--term test proved： the interface transfer rate may stably reach to 150 M/s, and the data is accurate and reliable, designed to meet the mission requirements.
