Quastions about Altera Ap372

Ok i understand how it works

The idea is good but need strong work to make normal LCD controller with good alpha support.

Unfortunaly alpha processing in this example is verry poor http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

And for gaming this core not good !!!!!!!

Can i ask some quastion to altera team who make this aplication note

Why you make 8-bit drawing layers ? what problem with 16bit drawing layers ?

And i want to know your opinion about reality of my planes to rebuilding this core

and what possible problems will be ?

I want to make 4 layers core

where

layer 1 is 32 bit layer with 8 bit per pixel alpha

layer 2 is 32 bit layer with 8 bit per pixel alpha

layer 3 is 32 bit background layer 1

layer 4 is 32 bit background layer 2

layers 1 and 2 for drawing and srtite processing with alpha channel (2 videopages animation)

Layers 3 and 4 - need to make background scrolling or animation (2 videopages animation too )

What you think is it real to make on one SDRAM x32 memory ?

or need to do separate SDRAM x32 videobanks ?Plus programm sdram ?

in this case on Cyclone_1C20 board is not possible to do it.
