<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am having trouble understanding the stack allocation
scheme when using a C55xx device. From what I can tell, the GLOBAL_STACK_SIZE
is set in arch.h to 100,000 bytes (when using FIXED_POINT), which is then used
in the ALLOC_STACK macro found in stack_alloc.h. This macro seems to say, if global_stack==0,
then call celt_alloc_scratch, found in os_support.h, which in turn attempts to allocate
(using calloc) 100,000 bytes for the global stack. However, the *celt_alloc_scratch
expects an “int”, which in C55x lingo is 16bits (+/-32768). When
debugging this macro, a value of -31072 is passed to *celt_alloc_scratch, which
allocates no stack, causing failure of celt_mode_create(). What am I missing?
Can you provide some insight on how the stack should be allocated? How large
should it be? 100,000 bytes seems a bit large to me.<o:p></o:p></span></font></p>
