Display List:

Row Attr. 48 bits x 15 rows = 720 bits

Char Attr. 16 bits x 30 chars x 15 rows = 7200 bits

The total display list is estimated based on the current OSD size of 30x15 characters.

Total Display List Memory => 7920 bits

TOTAL OSD Estimated RAM Memory: 82008 bits (RAM selected 98304 bits)

Color LUT:

64 x 32 = 2048 bits

For a 30x15 character display the OSD block global RAM has room remaining for:

Global 24b RAM is programmed in the following order:

Example

... and so on …..

Similarly, the Color LUT 32b RAM, is programmed in the following order:

Example

... and so on …..

255 => 1bpp (room for 418 char, but only 255 can be addressed w/ 8bit CID) or,

209 => 2bpp or,

139 => 3bpp or,

104 => 4bpp
