I have estimated memory bandwidth in following way:
480 (width) *
640 (height) *
3 (bytes per pixel, not sure) *
It's 2
25 (fps) == 23040000 bytes/s (22Mb/s)
60 fps however.
What kind of FPS is that 60? Display refresh rate?
Yes, the native refresh of the LCD is 60Hz.
Then it appears that we need 35Mb/s (480 * 640 * 2 * 60) for just
viewing picture on display? Sad :(
Simple two-layer fullscreen animation will need 26Mb/s (480 * 640 * 2
* 3 * 15),
where 3 == 1 (read back layer) + 1 (read front layer) + 1 (write result)
35 Mb/s + 26 Mb/s == 61 Mb/s
And what bandwidth can neo provide?
