Description: 直接频率合成DDS模块的ise工程，可以直接下载，在Spartan3/Spartan3E上验证通过。该DDS模块可以产生双通道的不同频率的正弦波，也可以产生同频的任意相位差的相移波形。本模块累加器位数为32位，可以产生12位相位精度12位量化精度的正弦波。该设计例化一个Block Ram，为节省储存空间仅需要储存1/4周期的数据。根据需要，可以重新修改数据，改变波形。-DDS direct frequency synthesizer module ，ise project, can be directly downloaded through the Spartan3/Spartan3E and tested successfully. The DDS module can generate two-channel sine wave of different frequency, or produce the same frequency arbitrary waveform phase difference of the phase shift. There is a 32-bit accumulator to generate 12 bit phase-precision 12-bit quantization precision of the sine wave. Cases the design of a Block Ram, in order to save storage space need to store only 1/4 cycle of data. Necessary, can modify data, change the waveform. Platform: |
