基于DSP+FPGA的高速数据处理与存储系统设计

Design of high speed data paralle processing and storage system based on DSP+FPGA

针对信号处理数据量大、实时性要求高的特点,从实际应用出发,设计了以双DSP+FPGA为核心的并行信号处理模块。为了满足不同的信号处理任务需求,FPGA可以灵活地选择与不同的DSP组成不同的信号处理结构,同时为满足大数据存储要求设计了可方便网络控制的数据存储模块。模块之间可以通过自定义LVDS接口实现互联,组成一个系统。

With the development of technical, data processing is characterized the theme as processing huge data and shorter processing time, especially real time processing are needed. Based on engineer need, a paralle signal processing card based on dual DSP＋FPGA was developed. In order to meet the demand of different signal processing, FPGA can choose to cooperate with different DSP to implement different framework flexily. We designed a solid state data storage with large capacity which takes Gigabit Ethernet as control interface. System can be formed by these cards with user-defined LVDS, and it can afford high-speed data transmission channel.
