摘　　要：为了解决先进雷达数据存储应用领域的带宽高、通道多、容量大、集成度高等难题,提出了一种基于FPGA的多通道数据源的NVMe固态盘存储阵列技术。存储单元设计成标准模块集成于雷达系统;以FPGA为核心芯片,采用双组内存同时并行读写数据以及双通道PCIe Gen3独立处理数据的方法,设计了复杂的逻辑功能模块,实现了大数据流的传输和处理,提高了存储带宽。该技术已经实际应用于工业环境下的雷达,经反复测试表明,单个存储单元能同时存储16路数据源,存储容量达24 TB,存储带宽达7 GB/s,可满足系统存储性能。In order to solve the problems such as high-bandwidth,multi-channel,large-capacity and high-integration in the data storage domain of advanced radars,a NVMe solid state disk storage array technology of multi-channel data based on FPGA is proposed.This storage unit integrated in the radar system is designed as a standard module.It takes FPGA as the core chip,which uses the methods of parallel double-group memory writing and reading data simultaneously,and dual-channel PCIe Gen3 processing data independently.And it designs complex logical function modules,achieves the transmission and processing for big data stream,and improves the storage bandwidth.This technology is applied to the radar in the industrial environment.The re‐peatable tests show that a storage unit can simultaneously store 16-channel data with the storage capacity up to 24 TB and writing bandwidth up to 7 GB/s,and can meet the system storage performance.
