What do you think? Could it be faster?

Subject is complete. I'm using emWin libraries on LPC1769 (OM13000 developer board) running at 120MHz (4MHz from IRC and main PLL configured with multiplier 45 and divider 3).
The interface with 320x240 TFT is 16-bits parallel bus.

I'm using GUI_DrawBitmap() every 1 second to draw a 320x240 image (full screen).

I expect a better performance.
