摘要：Direct Digital frequency synthesizer (DDFS) is a signal generation method and an essential part for localoscillators, mixers and modulators. This paper will introduce a DDFS architecture which is based on the scale freemicro-rotation CORDIC algorithm and its hardware realization is comparing with the pipelined CORDIC based DDFS.The frequency of the waveforms can be varied depending upon the applications. The design involves only shifting andaddition/subtraction operations and hence the complexity is reduced. The rotational mode operation of the CORDICalgorithm is used for computing sine and cosine values
