基于FPGA器件的DDS设计实现中的一个核心部分就是波形存储表的设计。首先采用LPM_ROM和 VHDL选择语句这两种方法进行波形存储表的设计和比较分析 然后考虑到硬件资源的有限性及DDS的精度要 求,对这两种方法的程序进行了优化 最后对这两种方法设计的程序进行仿真和硬件调试。结果表明:采用这两种 方法都能有效地实现DDS中波形存储表的设计。 (DDS-based FPGA devices designed to achieve one of the core of the waveform is stored in table design. First of all, choose to adopt LPM_ROM and VHDL statements of these two methods for the design waveform storage tables and comparative analysis and then, taking into account the limited hardware resources and the accuracy of DDS, the two methods to optimize the process the last of these two methods of process design simulation and hardware debugging. The results showed that: the use of these two methods are all effective ways to achieve the DDS waveform stored in the table design.)

在接收信号的数字化、软化的实现中,数字下变频起着重要的作用。本文首先介绍了数字下 变频的组成结构,然后详细分析了数字下变频的工作原理,描述了在实现数字下变频时,设计方案所 采用的高效滤波器———CIC 滤波器和多相抽取滤波器的结构和原理。最后,用通过Simulink 对数字 下变频的性能进行了仿真。在仿真的基础上使用Insight 公司的FPGA 开发系统,用测试电路实测了 数字下变频的性(In the receiving digital signal, softening the realization, the digital down-conversion plays an important role. This article first introduced the digital down conversion of the composition, and then a detailed analysis of digital down conversion of the working principle described in the realization of digital down conversion, the design used in high-performance filters--- CIC filters and multi-phase extraction filter structure and principle. Finally, with the adoption of Simulink for digital down-conversion performance of the simulation. In the simulation based on the use of Insight s FPGA development system is measured using the test circuit of the digital down-conversion of)
