Abstract: A memory initialization controlling apparatus reads memory control data that is control data which controls an input or output of data of each memory and initializes a memory controller that controls memories. The memory initialization controlling apparatus includes a memory comparison control information storing unit that stores memory comparison control information that is information which controls the comparison of the memory control data; an SPD data reading unit that reads the memory control data from the memories; and a memory initialization controlling unit that controls the comparison of the memory control data in accordance with the memory comparison control information, and initializes the memory controller in accordance with the results of the comparison.

Abstract: A graphic display apparatus includes a geometry transforming part for inputting graphic data of a target object and transforming the graphic data into coordinate values of a device coordinate system which is used by the graphic display apparatus, an area calculation part for calculating an area of a polygon which generates an image based on the transformed coordinate values of the device coordinate system, a shading technique selection part for selecting a shading technique corresponding to the area of the polygon calculated by the area calculation part from a plurality of shading techniques which are determined in advance depending to the calculated area, a luminance calculation part for calculating a luminance of the graphic data of the target object according to the shading technique selected by the shading technique selection part, and a dot developing part for developing the graphic data of the target object for which the luminance is calculated by the luminance calculation part into dots.

Abstract: An anti-aliasing line display apparatus includes an input device for inputting a coordinate and an attribute of an input straight line which is to be displayed, a judging device for judging a width and a slope of the input straight line, an analyzing device for decomposing the input straight line into individual pixels and setting a drawing pixel to be drawn, a distance calculating device for calculating a distance from a center of the drawing pixel set by the analyzing means to the input straight line, an occupying ratio calculating means for calculating an occupying ratio of the input straight line with respect to the drawing pixel based on the distance calculated by the distance calculating device, a frame buffer, a blending device for blending the color of the drawing pixel and a color input in the frame buffer in advance based on the occupying ratio and for writing the blended color in the frame buffer, and a display device for displaying the input straight line based on the color of the drawing pixel wr
