Hardware cursor
Coral supports two hardware cursor functions. Each of these hardware cursors is specified as a 64 ×
64-pixel area. Each pixel of these hardware cursors is 8 bits and uses the same look-up table as
indirect color mode.
Double buffer method
Double buffer method in which drawing window and display window is switched in units of 1 frame
enables the smooth animation.
Flipping (switching of display window area) is performed in synchronization with the vertical blanking
period using program.
Scroll method
Independent setting of drawing and display windows and their starting position enables the smooth
scrolling.
Display colors
• Supports indirect color mode which uses the look-up table (color palette) in 8 bits/pixels.
• Entry for look-up table (color palette) corresponds to color code for 8 bits, in other words, 256. Color
data is each 6 bits of RGB. Consequently, 256 colors can be displayed out of 260,000 colors.
• Supports direct color mode which specifies RGB with 16 bits/pixels.
