SPRITE PERFORMANCE Clause Samples

SPRITE PERFORMANCE. The minimum goal is 2000 sprites per update or 120K per second. The average sprite area is 16 by 16 pixels, or roughly 500K pixels per update, or 30M pixels per second. More sprites are desirable, such as 2500 or 3000 per update. Performance to draw the display image 8 or more times per update, or 640K pixels, is desirable. Sprites can be of any programmable area, within a performance limit of some maximum total number of sprites per update and total number of pixels per update. Sprite image data should be aligned on a pixel boundary (8 or 16 bit), so that no memory padding is needed.
