Direct digital synthesis (DDS) is a method to generate waveforms directly in the digital domain. In this method,the target waveforms are the sine and cosine ones. The Co-ordinate Rotational Digital Computer (CORDIC) algorithm configured in Rotation Mode (RM) can behave as a quadrature phase-to-amplitude converter that directly generates sine and cosine waveforms. The main advantage of using COR...

In this paper we compare implementations of Duprat and Muller’s Branching CORDIC and Phatak’s Double Step Branching (DSB)–CORDIC algorithms for Sine and Cosine evaluation. For reference we also report on classical CORDIC implementations for the same wordlengths. We have also implemented Double Stepping in the classical algorithm and report on the performance of this method. CORDIC evaluation of...

Digital sine and cosine waves have been used in countless applications in the field of vector rotated Digital Signal Processing (DSP). The COordinate Rotation DIgital Computer (CORDIC) algorithm has become very popular due to its simplicity in catering to almost perfect digital sine and cosine waveforms during modulation and demodulation processes in DSP modules. In this paper, we have presente...

The Clenshaw Curtis method for numerical integration is extended to semiinfinite ([_0, 30] and infinite [-0% oc] intervals. The common framework for both these extensions and for integration on a finite interval is to (1) map the integration domain to tc[0, z], (2) compute a Fourier sine or cosine approximation to the transformd integrand via interpolation, and (3) integrate the approximation. ...
