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.

A Row-After-Column memory addressing method. The memory addressing method changes the order of addressing so as to enhance the efficiency of memory addressing. The Row-After-Column memory addressing method of the present invention comprises the steps of activating a column path by generating the column address when the address is input for data access, and activating a row path by generating the row address according to the address. Therefore, pipeline stall arising from inputting the column address (/CAS) subsequent to input of the row address (/RAS) can be eliminated and the speed of memory access can be enhanced.
