摘要
为解决目前信号处理系统中数据传输的瓶颈问题,设计并实现了一种基于可编程门阵列(field programmable gate array,FPGA)的高速实时数据传输方案。该方案借助Xilinx FPGA的ChipSync技术,稳定地完成了数据的串化/解串,以及通信链路相对延迟的精确测量和调整。同时,利用提出的数据传输同步方法-系统同步和串行低压差分信号(low-voltage differential signaling,LVDS)总线技术实现板卡间大量数据的高速传送,有效地保证了多通道传输的同步性和可靠性,并大大降低了系统互联的复杂度和系统成本。
To solve the speed bottle-neck of data transfer in current signal processing system, a scheme for high speed data transfer was proposed and implemented based on field programmable gate array （FPGA）. ChipSync technology in Xilinx FPGA was used for data serializing/deserializing in the scheme, and relative delay of different channels was also tested and adjusted with it. Meanwhile, a method for transferring synchronization was proposed, which along with serial LVDS bus technology guarantees the reliability and synchronization of channels and reduces system complexity and cost greatly.
