Designing a Intuitive System with 1280x 800 LCD Interfaced with RGB 888 with Fluidic Animations

I want to design an Intuitive System with a 1280x 800 LCD interface with RGB 888 running Fluidic Animations and transitions (30FPS) Which system combination will work to create such a system? I figured it would require STM32H750 Or similar MCu with 32 BIT RAM Interface 24 Bits RGB Along with QUAD FLASH.

Excuse me but what means intuitive system? Yet another slate with a LCD and weird animations? "Intuitive" looks like this.

I want to know what is the maximum output of FPS that I can achive from STM32H750 running at 400MHz with 16bit Ram

At a resolution of 1280*800 at RGB888 , Can we achive decent frame rate and color dept.If yes what should we change to make the system better and if no what determines the FPS of the syste

For DSI displays is your limit two lanes every 500Mb = max 1Gbit/s equal to around 1280x800x3xFPSx8=1G

result around 40 FPS max RGB888. Better FPS for RGB565

For paralel RGB connected display you can arive more FPS limited with RAM access speed ...

But nobody reply you your question, because nobody have info what your system will do. 

So if I opt with 32bit ram with StM32H750 along with parallel RGB888 I'll be getting 40 fps?

Could you please share the calculation to find out the fps with resolution and ram bus width

calculated values dot clock is in table... from this number FPS= DCLK / (1280x800) for example 16bitram 24bit dma2d FPS = 38000000/1024000 = 37FPS
