Image Analyzer for grey scale image

Alexander Shlafer

Hello,

I need to show 16 bit gray scale image from DSP memory, The single way I found is to define RGB planar image format and to give the same start address for Green, Red and Blue components. This works, but the analyzer read the same memory 3 times and this take a long time. Is there any other possibility? It may be helpful to add this possibility in the next version.

    Hey, Alexander:

          I can't solve your problem but I got some question here, how did you put the image into the DSP memory? Is there any way to load a image into memory use CCSv5? In CCSv3.3, it have a function to load image into DSP.   I just want to handle picture within DSP but don't know how to do it.

           Thanks.

    Hi,

    I use stdio.h functions for working with files (fopen, fread, ...) when I work with ICE.

    Hi Alexander,

    The performance of the Image Analyzer is dependent on the speed of the connection between the debugger and the target. What emulator are you using? If you are using a slower emulator like XDS100, this would certainly impact performance negatively.

    Thanks

    I'm using XDS560v2, but when I need to read the image 1280*1024 pixels 3 times(RGB), it takes a long time.

    Is there any possibility to increase a clock speed of emulator?

    I am also experiencing this annoying problem. As we have lots of images in gray scale.  I've done some reserches on this, however, I still can't find any good solution talking about it.
