Abstract: A method and device for generating a clock signal with predetermined clock signal properties firstly prepare a number of clock signals with an essentially identical frequency and with a respectively different phase relation with regard to a master clock signal in order to subsequently (on the basis of a control signal, which is prepared according to the clock signal to be generated), select predetermined clock signals from the number of prepared clock signals and to combine the selected clock signals in order to generate the desired clock signal.

Abstract: A method for rasterizing a graphic primitive (120) in a graphics system generates, starting from graphic primitive description data, pixel data for the graphic primitive, the graphics system comprising a memory which is divided up into a plurality of blocks (a, a+1, b, b+1) which are each associated with a predetermined one of a plurality of areas on a mapping screen (114). Each block of the plurality of blocks (a, a+1, b, b+1) is associated with a memory page in the memory. The method includes scanning the pixels associated with the graphic primitive (120) in one of the plurality of blocks (a) into which the graphic primitive extends, repeating the preceding steps until all of the pixels associated with the graphic primitive have been scanned in each of the plurality of blocks into which the graphic primitive extends, and outputting the pixel data.
