Claims

For each sprite attribute table having a circuit indicating a display position of the sprite, pattern data for defining the sprite, control data for defining the display mode of the sprite, raster number and A first detection means for comparing the vertical position values of the coordinates, a sprite generator for storing the pattern data of the sprites, and a second comparing with the horizontal position values of the coordinates of the sprites displayed as dot clock signals for detecting the displayed pattern data And a means for controlling the screen to display the sprite displayed at the position according to the pattern data to be displayed.

2. The apparatus of claim 1, comprising means for controlling the change in coordinates of the sprite to move the sprite on the screen.

2. The screen of claim 1 comprising means for controlling at least one of said control data of said sprite attribute label comprising CGX and / or CGY instructions and a plurality of sprites connected in a horizontal and / or vertical direction. Device for displaying sprites.

2. A warning signal as claimed in claim 1, wherein said first detecting means for detecting less than a predetermined number of sprites displayed in a raster line, and generating a warning signal when said first detecting means detects more than a predetermined number of sprites displayed in said raster line. Apparatus for displaying on a screen consisting of the means for controlling the.

2. The apparatus according to claim 1, wherein the sprite is displayed on a screen composed of a pattern data buffer for storing pattern data of the sprite to be displayed.

6. The display according to claim 5, wherein the sprite is displayed on a screen composed of said means for controlling the generation of a warning signal when said pattern data of said displayed sprite is not transmitted from said sprite generator to said pattern data buffer in a horizontal retrace period. Device.

6. The apparatus according to claim 5, wherein said means for controlling the generation of a warning signal when said pattern data of said sprite exceeds a capacity of said pattern data buffer is displayed on a screen.

6. The screen according to claim 5, comprising means for storing standard coordinates of the display area on the screen, and means for controlling the sprite prohibition displayed according to a comparison between the standard coordinates with the position of the pattern data. Device for displaying sprites.

10. An apparatus according to claim 8, comprising said means for controlling said gate circuit to forbid said display of said sprite to be turned off.
