Towards a Taxonomy for Display Processors

  • Bengt-Olaf Schneider
Conference paper
Part of the Eurographic Seminars book series (FOCUS COMPUTER)


Image generation for raster displays proceeds in two main steps: geometry processing and pixel processing. The subsystem performing the pixel processing is called display processor.

In the paper a model for the display processor is developed that takes into account both function and timing properties. The model identifies scan conversion, hidden surface removal, shading and anti-aliasing as the key functions of the display processor. The timing model is expressed in an inequation being fundamental for all display processor architectures.

On the basis of that model a taxonomy is presented which classifies display processors according to four main criteria: function, partitioning, architecture and performance.

The taxonomy is applied to five real display processors: Pixel-planes, SLAM, PROOF, the Ray-Casting Machine and the Structured Frame Store System.

Investigation of existing display processor architectures on the basis of the developed taxonomy revealed a potential new architecture. This architecture partitions the image generation process in image space and employs a tree topology.
