AM5728 drawing performance

Hi,

I have one question regarding AM5728 drawing performance.

My customer would like to increase the performance of BitBlt and window drawing.

For this reason, customer changed the data format from RGBA8888 to RGB565. 

But the result was not so good. The drawing performance increased the only 3%.

The color format is changed from 32 bit to 16bit. This means data volume is half. I think the drawing performance should go up more.

Could you advise the reason of lower performance?

I appreciate your quick reply.

Best regards,

Michi
