Improving graphic performance

Other Parts Discussed in Thread: OMAP3530

Hi,

I have a OMAP3530 custom board with WINCE 6.0 R3 / BSP ARM_A8_01_01.  I need to know if I have configured the BSP correctly to get the best display performance possible with this platform.  Our application engineer asks for better graphic performance.

In lcd_vga.c, I use

 

 

DISPC_PIXELFORMAT_ARGB16,

//pixelFmt;
1280, //width;
720, //height;

 In the catalog, I have the followings checked:

- All items under Third Party/PowerVR

- VRFB driver under Drivers/Display

- None under Third Party/Texas Instruments

The registry file dss.reg is modified for 90-degree rotation.  Please give me your advice on anything else that I can do.

Thanks,

Luan

    I think you have got all the settings right. What type of performance impact are you seeing and under what conditions? With 3530 and rotating a big display of size 1280x720 by 90 degree, you may see some performance issue due to memory/CPU bandwidth limitations.
