interleaved image to planar image

interleaved image to planar image

I am doing image processing on a P4 processor.

The image are interleaved 8 bit integers i.e (rgbrgbrgb...) when I get the images but it is much easier to perform fast processing using sse when the image is planar (rrrrrggggggbbbb...) I would like to do this conversion. Does anyone know if the source code for a conversion is available anywhere? The code will be quite short but I would like to do other things than optimizing this if it is possible.
Any suggestions how this should be done as fast as possible? is SSE fastest?
