Jean-marc, I am trying to port CELT to the ti dsp c5515. I counted a problem when I try to call a function: len = celt_encode(enc, in, frame_size, data, bytes_per_packet); I guess that the problem in the stack allocation variable defined in the header file stack_alloc.h. For more info over my platform settings, see the attached files. May be the global_stack variable is not good configured or not good defined. Could you telling me if my configuration is OK, please?

...es the stack from the nb en/de-coder. But the echo-canceller and preprocessor don't use it. I suppose they also have some scratch buffers. (comments in SpeexEchoState_ structure mdf.c) But you allocate them with speex_alloc instead of using the VARDECL/ALLOC macros. Converting the code to the stack_alloc mechanism could result in better performance with a scratch buffer in SRAM. I think I can do it for mdf.c, but I would need information for preprocess.c. -- St?phane LESAGE ATEIS International

Hi, In case it is of any help, to compile a static library for the iPhone, I had to add the following 2 lines in plc.c file : #include "arch.h" #include "stack_alloc.h" otherwise "celt_word16..." type are not defined and "VARDECL...." also not. Best Regards St?phane Letz

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 debu...

...c to set this value only if it was not already defined, and then put my own, much smaller value in config.h. For the scratch stack, I replace the fixed values in nb_encoder_init and nb_decoder_init with constants that I defined in config.h. Jamey Hicks original C5x patch had some test code in stack_alloc.h to detect working stack overflow. Maybe something similar could be done to measure the peak stack usage, enabled by a debug switch. Then, for a space critical application, it would be easy to measure the stack requirement for a given operating mode, and set the size (manually) accordingly....

Jean-Marc, Thanks for the response and the helpful info. I am trying to get the library to build without using the pseudostack define, and use either VAR_ARRAYS or ALLOC, but it seems the global stack is not defined. Where do can I define this in my example? VR -----Original Message----- From: Jean-Marc Valin [mailto:jmvalin at jmvalin.ca] Sent: Tuesday, February 20, 2018 5:40 PM To:

Dear Nikos, thanks! But you use Opus only for resampling, not for entirely replacing Speex, don't you? Greetings!

HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to

...ur compiler supports C99 VLAs, then by all means just define VAR_ARRAYS and you're good to go. If not, the second best option is alloca(), which you can use by defining USE_ALLOCA. If your compiler supports alloca() and USE_ALLOCA doesn't work, then you may need to make minor tweaks to celt/stack_alloc.h. Do not use NONTHREADSAFE_PSEUDOSTACK unless all other options fail.
