基于DSP与FIFO的多路雷达数据转换系统设计

The System Design of Multi-Switch Radar Signal Convert Based on DSP and FIFO

在处理多路高速雷达信号过程中,数据的采集和存取是最重要的环节之一.由于DSP的工作时钟和A/D的采样速率不同,为了提高DSP的工作效率,避免丢失数据,就采用FIFO作为两者之间的接口.阐述了基于FIFO与DSP的雷达高速数据转换系统的设计思想,并给出了FIFO处理数据的程序流程.

In the process of dealing with multi-switch radar signal, data collection and access is one of the most important process. Because the working clock of DSP and sampling rate of A/D converter is great different, in order to advance the efficiency of DSP and avoid losing data, FIFO is used for the interface between them. The design thought of multi-switch radar signal convert with high speed and a soft flow of data process are introduced.
