I have a speed problem with emWin. I have board with a 7 inch 800*480 24bit TFT and the LPC1850(flash less part).The processor and the LCD are connected via 24 lines. But performances are bad. Everything work very slow (Bit map update takes around 5sec for 24bit image ). I have external NOR flash and SPIFI in my board, Processor is running at 180MHZ and SDRAM at 90MHZ, SPIFI 90MHZ.  Images are stored in SPIFI. I'm using triple buffering with SDRAM. What are the recommendations to increase speed
