Abstract :
A floating point geometry engine core is introduced in this paper. The proposed core is optimized for performing the 3-D geometrical transformations, including the hardware evaluation of sin x and cos x functions. The architecture exploits the structure of the transformation matrices, thus reducing the number of floating point operations required per transformation. VLSI chip implementation issues for the specific architecture are also discussed
