The Optimal Implementation of a Generator of Sinusoid

The embedded systems occupy a place increasingly important in our daily life. In recent years much of research it is focused on the miniaturization of the various electronic devices. In this study we present the architecture of a digital generator of frequency based on trigonometrically algorithm to obtain sample high frequencies. We treat a comparative study between various processors CORDIC: Iterative, pipeline, pipeline without accumulator of phase and parallel. The objective of this study is to find the best sampling frequency and the throughput. This will allow the establishment of a generator of sinusoid. The results which we got show that parallel CORDIC is most powerful. This best algorithm increases the effectiveness of the digital modulator in order to optimization of system of data transmission to high-speed in telecommunication.
