JPEG Gui icon without Touch GFX on stm32h7

MMARI.1
Senior

hi,

I am currently using BMP + rgb565 LTDC display for GUI icon creation without Touch GFX ( Everything is on "" C"" only and Manual preparation icon using hex converter ).

Already known one is ! for a small size ,BMP is OK but large size BMP icon  will increase the size and processing time  .

MMARI1_0-1755258457457.bmp   

Above Picture size is 6.30KB in BMP                                                

MMARI1_1-1755258542949.bmp

Above Picture size is 2.03KB in JPEG      

Visually i could not see any difference  BMP and JPEG in my laptop   .

Now i am using internal memory for small icon  (Now working with stm32h723zgt6 and plan to upgrade to stm32u5 series )

Please clarify my doubts. 

0. Can i use Hardware Inbuilt JPEG decoder for JPEG  GUI icon creation with rgb565 format  ? . 

1. Do you think i can achieve best frame rate by  Hardware Inbuilt JPEG decoder ?.

2. Either i will get same picture quality like BMP in Hardware Inbuilt JPEG decoder ?
