hi,
is there any limitation on the size of the stcak on 6X EVM. Can I have a
stack size of as high as 15kB? what is the effect of putting the stack on SDRAM
apart from slowing down the execution of the code?

Rajesh, I fairly sure that a large stack will work fine. I haven't tried it, but I do know that the stack pointer is 32bits, so you should be ok. Having the stack in SDRAM will slow down the code - you are correct. I think you would want to turn on L2 cache if you are planning to do this. - Andrew E.

Hello Rajesh,
Andrew is correct, the c6x devices can handle large stacks.
I will offer a couple of comments:
If your board is a TI 6201 or 6701 EVM, you have three logical places to
put the stack
1. SDRAM - the largest and slowest 2. SBSRAM - faster but smaller
3. Internal Data RAM - 64KBytes, the smallest and fastest
I would suggest using SBSRAM [unless you can squeeze into the internal data
RAM].
Any external RAM will add some latency for every stack access. After
you get your app running, you can rearrange where your stack lands in memory and
measure the results.
