摘要
高速实时信号采集系统是由高性能ADC、FPGA和QDRⅡSRAM等组成。其中高性能ADC实现模数转换,FPGA与QDRⅡSRAM实现ADC信号的接收、数据重组、存储和传输。重点讲述了FPGA如何接收采样率为2 GS/s的高速ADC数据并保持一定的时序裕量,并通过分析FPGA中资源占用情况可以看到FPGA在高速实时信号采集系统中具有很大的优势。
The high-speed real-time signal acquisition system is composed of high performance ADC,FPGA and QDRII SRAM.ADC plays a role of analog-to-digital conversion.FPGA and QDRII SRAM are used to receive, reorganize,store and transfer data from ADC.How FPGA receives high-speed ADC data with 2GS/s sampling rate and keeps enough timing margin are focused on.FPGA has great advantages in high-speed real-time signal acquisition system through the analysis of FPGA resource usage ratio.
