ABSTRACT:
A system updates the z-values corresponding to pixels of a computer graphics screen. An integral part of the system comprises a controller/memory module which employs preliminary determinations as to whether or not a z-value has been previously stored for a pixel, multiple comparators, and partial read and write operations to achieve a significantly higher memory bandwidth. The bandwidth can be further increased by configuring a plurality of such modules in a parallel architecture.
