    Hello Meriem,

    Here is a resource that will be helpful for you: These are notes about using the function generation function of the C6713 DSP.
    Good luck!

    Meriem,

    A lot depends on how accurate you need the sine wave to be.  Search for this paper:

    Effect Design Part 3 Oscillators: Sinusoidal and Pseudonoise by Jon Dattorro.

    He covers

    2D PLANAR ROTATION
    MODIFIED COUPLED FORM
    DIGITAL WAVEGUIDE RESONATOR (DWR).

    I use the coupled form to produce a very high quality sine wave.
