【 摘 要 】

The embedded systems occupy a place increasingly important inour daily life. In recent years much of research it is focused on theminiaturization of the various electronic devices. In this study we present thearchitecture of a digital generator of frequency based on trigonometricallyalgorithm to obtain sample high frequencies. We treat a comparative studybetween various processors CORDIC: Iterative, pipeline, pipeline withoutaccumulator of phase and parallel. The objective of this study is to find thebest sampling frequency and the throughput. This will allow the establishmentof a generator of sinusoid. The results which we got show that parallel CORDICis most powerful. This best algorithm increases the effectiveness of thedigital modulator in order to optimization of system of data transmission tohigh-speed in telecommunication.
