[Books] DDS DL : 0: 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.
