基于DSP和FPGA的数据采集记录与处理硬件设计

Hardware Design for Data Acquisition and Recording and Processing Based on DSP and FPGA

为应对雷达接收通道增多和数据处理与记录实时性要求提高等问题,设计并实现了一种使用DSP与FPGA配合完成数据采集分发和记录任务,同时使用DSP阵列进行大规模信号处理的硬件系统。多次飞行试验结果表明,该设计数据吞吐量大、实时性强、性能稳定、工作可靠,具有很大的推广价值。

The increasing amount of radar receiving channels brings more echo data streams and results in higher level request of real-time data processing and recording.To fulfill coherence to before-mentioned improvement, a hardware design based on DSP and FPGA has been proposed.FPGA is in charge of data acquisition and recording,and large DSP array is used to perform data processing arithmetic.Many flight tests show that the new hardware design deserves widespread application,with large data throughput and stable and good real-time performance.
