Thresholding program required

i am using ti c6416 DsP thru which i am doing Image processing that is captured online. can anyone provide me with a sample program how to do thresholding or suggest any site that helps in thresholding?

Hi,
I don't know how you are going to use thresholding. If you just do some test, you can implement it in a few lines of code. If you want to use it in your product, it is very easy to optimize it and may you can also use the functions provided by TI. Please refer to the following manual:
TMS320C64x+ DSP Image/Video Processing Library Programmer’s Reference
(SPRUEB9)

Hi,

I am trying to profile an audio codec on C6713 DSK. Can somebody
help me on how to do this?
I tried to use profiler along with CCS, but it is really really slow and I
am not sure whether it is possible to use that or not.
Is there any timer functions which I can use in my code to get the clock
cycles?

Regards,
Arun

Yes you can use the internal timer to profile your code

Is there any inbuilt functions to use this timer? Or do I need to configure
it myself?

Hi all,

I am working with C6713 DSK. I have strange problem with malloc. I
have mapped the .sysmem into internal memory and the .rtstext to external
memory. But When I am moving the rtstext to external memory, the 'malloc'
call is failing and it always return NULL. Does anybody knows what is
happening here?

regards,
Arun Sankar M

You don't mention how much space you attempt to allocate at runtime with the
malloc call, or how much space is allocated for the heap in the linker
stage. I would expect the problem is not enough space to satisfy your
runtime request.

I am allocating enough heap and the program works fine if I am keeping the
rtstext inside internal memory. And more over I am trying to allocate only
256bytes of memory in the first malloc and I am keeping a heap size of
0x16000. So definitely it is not the problem with heap size, right?
