As long as you make those buffers global (static) you shouldn't have
too much of a problem. Stack will be a problem if you try to allocate
them within a function (i.e. on a stack frame). The alternative is to
use something like malloc() which will allocate them on the heap, but
your heap would need to be configured then as wll to make sure it was
big enough. That's not difficult, but...

Hi,

I have a piece of real time speech enhancement software running and i want
to store a few minutes of the in and out buffers on memory.  What is the
safest recommended way of allocating a large chunk of memory using Code
Composer Studio that wont smash my stack all to bits or cause other
problems. Basically what i want to do is:

#define BUFFERSIZE_BYTES 1000000

char in_buff[BUFFERSIZE_BYTES];
char out_buff[BUFFERSIZE_BYTES];
....

Whats the best way?
