Computer graphics apparatus utilizing cache memory |
摘要 |
In a computer graphics apparatus, a main memory stores image data representing pixels on a raster scan display. A cache memory is provided for retaining a partial copy of the image data in the main memory. A computing unit processes the image data copied into the cache memory. A video cache memory acquires image data from the main memory and the cache memory. A graphics controller acquires image data from the video cache memory and outputs the image data to the raster scan display.
