any one know how to add this kind of bump in cycles?
That's not a Bump map but a Normal map. The goal is similar (adding depth), but they work different.
A Bump map is a grayscale picture, where the black pixels mean "hollow" and the white pixels mean "bump".
A Normal map is a color picture, where each color channel (Red, Green, Blue) mean that the normal of the face is oriented along an axis (X, Y, Z).
