摘　　要：以高性能ADC芯片及超大规模可编程门阵列(FPGA)芯片为核心器件,利用其高度的灵活性及强大的处理能力,构建了一套通用的数字信号处理硬件平台,可处理载波频率小于200MHz,带宽小于20MHz的所有中频信号。并通过显示面板驱动七段数码管、发光二极管、按键等常用输入接口器件,极大地提升了平台的可扩展性及可重构性。Based on the high performance ADC chip and large scale FPGA as the core device, using its high flexibility and strong processing ability, this paper constructs a set of general digital signal processing hardware platform, which can handle the intermediate frequency signal whose carrier frequency is less than 200MHz and whose bandwidth is less than 20MHz. Through the display panel, it can drive seven digital tube, light emitting diode, buttons and other common input interface device, thus greatly improving the platform extensibility and reconfigurability.
