Abstract: Experiences with the realization of an object processor using a silicon compiler will be described. Object processors are parts of the object oriented display processor architecture PROOF (Pipeline for Rendering in an Object Oriented Framework; [9] and [8]). Placed in an object processor pipeline the object processors perform the scan conversion, the interpolation of the depth values and the normal vectors of the primitive objects of a scene to be rendered. The suitability of the silicon compiler GENESIL1 for the development of graphics hardware will be examined using the object processor as an example.
