ADDRESS GENERATOR, IMAGE DISPLAY, ADDRESS GENERATION METHOD AND IMAGE DISPLAY METHOD.

摘要

The image data read out from a VRAM (18) are supplied to a selection synthesis section (63) through line buffers (75a to 75d). The line buffer (75d) stores the image data supplied from outside and supplies this image data to the VRAM (18). The VRAM (18) writes the image data supplied from outside through the line buffer (75d) and reads out this image data on the basis of the addresses from a control section in the same way as other image data. Cache memories (74a and 74b) read out the image data under the control of the control section (71) and display a plurality of tile-like images on the screen of a display.
