Silverlight performance question on WEC 7 Update 3, OMAP 3530

Other Parts Discussed in Thread: OMAP3530

Hi, all,

I was using Silverlight to build some applications and noticed the followings:
My envirnment is OMAP3530, WEC 7 update 3 with BSP 1.01.00.03, 800x480.

1. Simple animation moving a circle from left to right.
- Set BSP_XRPLUGIN_OPENGL=0, the circle is moving smoothly from left to right.
- Set BSP_XRPLUGIN_OPENGL=1, the animation seems a little bit "jumpy" when moving from left to right.

2. WEC 7 Sample Home Screen Theme 2
- Set BSP_XRPLUGIN_OPENGL=0, the background animation and the transition effect ran very slowly.
- Set BSP_XRPLUGIN_OPENGL=1, the background animation ran fine, but the transition effect is still "jumpy".

I was really confusing how to determine whether the "jumpy" issue is a right behavior or not.
Is there any standard performance result I can refer to?

Thank in advance,

Richard

    BSP 1.01.xx is meant for WinCE6 and not WEC7. Are you sure you are using BSP 1.01. If you are, can you try with BSP 2.00.xx with WEC7 (can be downloaded from here http://www.ti.com/tool/WINCESDK-A8) and see if the result is similar or not. Please note that other than the BSP, the PowerVR version between the 2 is different as well.

    The silverlight apps (bounce, bubble, carousel) run smooth on WEC7. The procedure to run these is given here http://processors.wiki.ti.com/index.php/WinCE-BSP_ARM-A8_User_Guide#WEC7_BSP

    Hi, Jatin,

    I get this WEC7 built from the OEM. May be this is a migrated version from WinCE6 BSP 1.01.xx.
    The DDK version of PowerVR is using 1.7.17.4352.

    I have follow the wiki instruction and copy all those files to windows directory.
    But with no luck, after run xamlperf in cmd window.
    It didn't show anything.
    From the terminal console, I got the following error message:

    PID:07FD0152 TID:06DC0152 ERROR: C:\WINCE600\public\common\sdk\inc\XRPtr.h line 33: PID:07FD0152 TID:06DC0152 HR=0x80004003 XRPtr Error (You are about to dereference a NULL pointer!) in XRPtr<class IXRUIElementCollection>::operator ->PID:07FD0152 TID:06DC0152 Exception 'Data Abort' (0x4): Thread-Id=06dc0152(pth=c04e7c18), Proc-Id=07fd0152(pprc=c04e9358) 'xamlperf.EXE', VM-active=07fd0152(pprc=c04e9358) 'xamlperf.EXE'
    PID:07FD0152 TID:06DC0152 PC=00013080(xamlperf.EXE+0x00003080) RA=0001307c(xamlperf.EXE+0x0000307c) SP=0002fbd0, BVA=00000000

    If those demo can be ran, what FPS will be expected?

    Thanks,

    Richard

    I found that that only" bounce.xaml" cannot be executed.

    However, the demo "carousel.xaml" seems "jumping" after the animation of the icon is played(clicked on the icon).
    What is the possible reason related to this issue?

    Thanks,

    Richard
