ABSTRACT:
Disclosed is a division unit for use in a three-dimensional (3D) computer graphics system. The division unit can reduce an area and power consumption thereof by removing more significant bits from homogeneous texture addresses u and v by the number of leading zeros included in a homogeneous texture address w and approximately carrying out a division operation for decreased data in texture mapping of the 3D computer graphics system. Therefore, the performance of real-time texture mapping is enhanced in a portable device operating at low power and hence 3D computer graphics can be realistically implemented.
