A matrix transform processor (MTP) for an Evans and Sutherland LDS-2 graphics system has been designed and built at the University of North Carolina. The MTP performs all the important functions of a matrix multiplier, clipper, and perspective divider. Because of fast division logic in the MTP, the clipping and perspective division algorithms are straightforward and the machine is quite simple. One processor handles all the functions; it is not necessary to pipeline the processes. The worst-case line processing time is about 10 ?s.
