Another Error For TI C55x C Compiler
hey guys, I am using the tip of Git and attempting to compile for a C55x
DSP. I am running into a couple compile errors and have found the source of
the issue.
The errors:
"celt.c", line 957: error: declaration may not appear after executable
statement in block
as well as

ask some questions about opus
Dear Sir,
Very glad to send E-mali to you , Im Annie.
I have encountered some problems on the way of learning opus, so I would like to consult you. I found "global_stack" was not released after malloc, and malloc memory was too large.So what I want to ask you is whether "global_stack" malloc can have less memory, since the value "GLOBAL_STACK_SIZE" can be

fixed point code
Hi,
I am looking into fixed-point code of the CELT decoder for real-time application. Here are some questions..
[1] array, window[]
The array, window[] is being initialized from a function below in modes.c. This array is being initialized differently for the decoder, depending on frame size and sampling freq. of the bitstream ..
Could you provide us with fixed-point code for initialization of

stack + heap sizes
??
hi ?Jean-Marc,
?
thanks for your answer.
But still I am struggling to find a reasonable upper limit for the RAM sizes.
?
You say we need 4.5/9.0 kB for enc/dec per channel.
But are those sizes really independent of any settings, like frame_size,
bitrate, complexity, etc. ?
?
at least in our configuration I find these requirements:?
?- native stack: < 2.1kB (enc or dec) measured by RealView

Porting CELt to the C5505
Tony,
How is this going? Have you been able to get CELT to run on a TI55xx? I am
very interested in the % utilization of the hardware and whether multiple
instance of CELT on the same DSP are feasible. I look forward to your
findings.

Memory Size?
In order to determine the optimum heap size requirements for my embedded
C55xx design, I have used the following to get the encoder and decoder
memory requirements:
size = opus_encoder_get_size(config.channels);
enc = malloc(size);
error = opus_encoder_init(enc, config.Fs, config.channels,
config.application);
size = opus_decoder_get_size(config.channels);

Global stack on Cortex-M4
Hi all !
I just learned about the Opus codec and would like to try it out on my
NRF52 (Cortex-M4) target. I've been struggling a bit with the
"trival_example.c" setup but repeatedly run into "hard fault" crashes
when stepping through the code.
Firstly; for a "bare bone" configuration, does the following compiler
directives make sense ?

Static Variables?
I am trying to get CELT running on a TI 5515 and am having trouble creating
a heap large enough to accommodate all of the dynamically created variables.
In fact, I would much prefer to have all variables created statically. Could
someone give me a short tutorial on what I need to do the create all of the
requisite variable statically?
Thx,

C55xx Linking Error
I am attempting to port CELT to the TI C5515 DSP. I am
compiling/assembling/linking with Code Composer Studio 4. I have enabled the
TI_55 specific optimizations in my config.h file per this

However, I am getting several "undefined symbol" linking errors that do not

(no subject)
Jean-Mark, Tim,
Could either of you expound on the following comment in cwrs.c?
/*If _k==0, the following do-while loop will overflow the buffer.*/
----------------------------------------------------------------
...because the following do-loop does overflow the buffer when k=126
k=2;
do _u[k]=(k<<1)-1;
while(++k<len);
Thanks,

API Change
Hi everyone,
I've just changed the API for CELT, but at least there's a good reason
for that. It's now possible to use the same mode data for both mono and
stereo. So here's the change:
- The celt_mode_create() function has a "channels" parameter
- The celt_encode_create() and celt_decoder_create() functions now have
an additional "channels" parameter.
- I

Allocating all memory up front
Hi guys,
I'm currently working on a CELT implementation for FMOD, and one of the
things we want to do is have all memory required allocated beforehand.
This is before we have any information about what sounds will be played.
We would like to create all of our CELTDecode instances up front.
Because celt_mode_create() requires a sample rate and number of channels
passed in, this

int operation
Gents,
My TI C55xx complier is complaining about (in opus_encoder.c,
opus_encode()):
st->silk_mode.payloadSize_ms = 1000 * frame_size / st->Fs;
where .payloadSize_ms is opus_int, frame_size is an int, and Fs is a long.
Should one of these be cast differently?
Thx,

Crash when using odd frame size
Hi
I noticed a crash issue when I passed the following values:
celt_mode_create(96000, 258, &e);
CELTMode->mdct.kfft[0] is not initialized after calling?clt_mdct_init() and when?celt_mode_destroy() is called it tries to dereference this value in kiss_fft_free().

Here's the callstack:

Endianess Switch?
Jean-Marc,
It appears that since testcelt reads a WAVE file from disck and passes the
data directly to celt_encode, so that celt_encode's "in" buffer must be
expecting little-endian formatted packets. Is this correct? Is there
endiness switch somewhere?
Thx

uint decode error on visual studio...
Is this a common warning? The decoder doesn't return an error on it, but I
see it a lot in my test application on windows. It is non existent on my
linux box. I haven't tried mingw yet.
please note that I'm using visual studio 2008 w/the vcproj that Bjoern
Rasmussen made for 0.5.2 (w/some file references removed) at the moment and
it is giving a lot of C4554 warnings

Porting CELT to the C5515
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

Frame_size?
"frame_size = PCM audio in signed 16-bit format (native endian). There must
be exactly frame_size samples per channel."
Sorry for such a simple request, but could you please clarify the definition
of frame_size when using stereo audio channels? When you say "frame_size
samples" does this mean that, if my frame_size is defined as 128, there are
64 left samples and 64 right
