摘要： PURPOSE: A system and a method for processing bump mapping are provided to reduce the amount of computation with respect to bump mapping using polar coordinate system. CONSTITUTION: A system for processing bump mapping includes the first and second computation units and a memory. The first computation unit receives a direction vector value of an incident light with respect to a polygon to be mapped, an intermediate vector value of the direction vector value and a point vector value, and a vertical vector value, and converts the direction vector value and intermediate vector value from a three-dimensional object space into a three-dimensional bump space. The memory stores a bump vector map having a perturbed normal vector value of pixels for the polygon and a look-up table having parameters. The second computation unit receives the converted direction vector value and intermediate vector value from the first computation unit and reads the perturbed normal vector value and required parameters from the bump vector map and memory, to compute a color value of each pixel of the polygon.

摘要： A pipelined divider with a small lookup table is disclosed. The pipelined divider can greatly reduce the size of a lookup table with a low cost to overcome the problems involved in the conventional pipelined divider requiring a large lookup table due to its iterative operation type. The pipelined divider has a delay time of 3 cycles in a single precision, and can reduce a chip size by about 1/3 in comparison to the existing pipelined divider.

摘要： PURPOSE: A method for calculating a trigonometric function using a linear equation is provided to reduce an error range through a linear equation, thereby promptly generating video of better quality. CONSTITUTION: A section of an X-axis in a trigonometric function curved surface is equally divided. Values of crossing points where vertical straight lines at boundary points of the divided sections cross the trigonometric function curved surface are obtained. Values of a trigonometric function to values of the sections are obtained by using a straight line equation connecting neighboring points in the obtained crossing points. Color values of fragments are decided by the obtained values of the trigonometric function. The section of the X-axis in a trigonometric function curved surface ranges from 0 to 90 deg.

摘要： PURPOSE: A pipelined ALU(Arithmetic and Logical Unit) having a lookup table of a small size and an operation method thereof are provided to decrease the size of the lookup table while increasing a delay time by one cycle. CONSTITUTION: A dividend X and a divisor Y have a regulated fixed point. The lookup table(LUT2) stores internal parameters and calculates the 1/(Yh)¬2 by using the divisor. The first multiplier(MUL3) calculates the divisor A by multiplying the 1/(Yh)¬2 of the lookup table to the (Yh-Y1) obtained from the dividend X and the divisor Y. The second and the third multiplier(MUL4,MUL5) calculate and output the AX and the AY by respectively operating the divisor A to the dividend Y and the divisor Y. The fourth multiplier(MUL6) outputs a quotient Q by operating the AX to the bit-inverted 2-AY.
