PROBLEM TO BE SOLVED: To speed up drawing processing of graphics hardware. SOLUTION: This graphics hardware has: a graphics engine 10 performing the drawing processing by use of pixel data; a frame buffer 14 storing pixel data supplied to the graphics engine 10, and capable of performing burst transfer of the pixel data; a pixel cache 11 performing input/output of the pixel data in a unit of a dimensionally changeable tile area obtained by dividing a storage area of the frame buffer 14 in a tile state, and supplying the acquired pixel data to the graphic engine 10; and a memory controller 12 converting an address outputted when the pixel cache 11 accesses the frame buffer 14 into a physical address of the frame buffer 14, and intermediating the access. The memory controller 12 converts the address such that the pixel data inside the tile area are stored within the same page area of the frame buffer 14. COPYRIGHT: (C)2006,JPO&NCIPI |
