In an MCU ,how to reduce bus bandwidth occupyed by LCD controller?And how to evalate the result?THx
 

You could have a dedicated bus from memory interface to your LCDC to releave bus load. Both memory interface and LCDC need to be redesign for sure...
 

The only way you can reduce the bandwidth that the LCD requires is to reduce resolution or color depth...
Otherwise, you can look into various ways of satisfying said bandwidth requirement.
