Hi all,
I need to implement RGB interpolation from a raw bayer image from CMOS camera
module.
It is more comfortable for me to store the raw data into a
multidimensional-array, like image[x][y] with x and y are the image pixel
coordinates, as it is applicable with C++ or C#. But is it also the right
solution in dsp platform? Because i am thinking of limited memory allocation in
dsp whether it could store for example 5 mega pixels image. i am using C6713 DSK
with DSK-eye daughtercard.
Thank you,

It looks like that you ran out of memory. What you have is a math problem.

Your heap is defined as 15,728,640. How did you determine the size??
How much memory is on your board?? 16M?? you will need to know this.
You will need to look at your memory map and determine the how much
SDRAM is being used by your code. Your 'heap size' can be no larger
than 'SDRAM_size' - 'SDRAM_memory_used_by_code_including_stack'.
