FLOATING-POINT PROCESSOR FOR THREE-DIMENSIONAL GRAPHIC ACCELERATOR INCLUDING SINGLE-PULSE STEREOSCOPIC PERFORMANCE

摘要

PROBLEM TO BE SOLVED: To improve a stereoscopic display function by saving a received geometric primitive in a buffer until it is accessed by a deformation unit during the generation of a 2nd deformed geometric primitive. SOLUTION: A command block 142 receives a graphic command and data from a host CPU through a host bus 104. When a stereoscopic mode is made usable by a CPU for the received specific primitive, a command block 142 transfers information wherein the primitive is described to one of floating-point processors 152A to 152F and also instructs a stereoscopic mode. The selected floating-point processor 152 operates in two series for a left-eye visual field and a right-eye visual field as to the received primitive. Primitives corresponding to the left-eye visual field and right-eye visual field are transmitted to a drawing processor 172 and stored in a frame buffer.
