Step 2 : Display the frame buffer
• The frame buffer is transferred to the display through a
dedicated hardware interface
• Graphical oriented microcontroller are offering a TFT
controller to drive directly the display
• The frame buffer must be sent at 60fps to have a perfect
image color and stability (independently from the animation
fps)
Step 1 : Create the content in a frame buffer
• The frame buffer is build by composing graphical primitive
• This operation is done by the CPU running a graphical
library software
• It can be accelerated by a dedicated hardware used with
the CPU through the graphical library
• More often the frame buffer can be updated, more fluent
will be the animations (frames per second / fps)
