Möller, ReinhardFons Kuijk and Wolfgang Strasser2014-02-062014-02-0619873-540-50109-61727-3471https://doi.org/10.2312/EGGH/EGGH87/111-121This paper compares two realized concepts of floating point units in a visual system for a traffic simulator. The hardware structure of a Transformation Processor is described, with which a set of 1x4 vectors can be floating point multiplied by a 4x4 matrix autonomously in real time. It will be shown, that the speed of graphics computations can be advanced enormously by using specially designed parallel graphics hardware but also requires the elimination of some design constraints given by the available building blocks in VLSI design today.
