These are all of the changes and additions necessary to build a loopback application for the
|
||
|
|
TI C6415, C5509A, or C5416 simulators using the TI Code Composer Studio (CCS) development system.
|
||
|
|
A trial version of the tools can be downloaded from the TI website.
|
||
|
|
|
||
|
|
This build runs 8kbps narrowband, with minimum complexity.
|
||
|
|
|
||
|
|
Several changes are introduced in Speex 1.1.11 which are used in these applications:
|
||
|
|
|
||
|
|
arch.h: Added switch for compilers not supporting "long long" (C55x does, C54x, CCS 2.x C64x does not)
|
||
|
|
bits.c: Allow external definition for max buffer size, changed MAX_BYTES_PER_FRAME
|
||
|
|
to MAX_CHARS_PER_FRAME for consistency
|
||
|
|
misc.c: Added override switches to alloc routines, conditional include of user file "user_misc.h".
|
||
|
|
These changes allow manual memory allocation rather than using heap
|
||
|
|
|
||
|
|
The arch.h change allows operation with 2.x versions of Code Composer Studio.
|
||
|
|
The bits.c change reduces the data memory usage.
|
||
|
|
The misc.c change allows private memory allocation, for cases where it is not
|
||
|
|
desirable to use the normal heap.
|
||
|
|
|
||
|
|
Added files:
|
||
|
|
|
||
|
|
testenc-TI-C5x.c (For C54x and C55x builds, derived from testenc.c,
|
||
|
|
manual alloc, byte packing/unpacking added)
|
||
|
|
testenc-TI-C64x.c (For C64x builds, derived from testenc.c, manual alloc, byte packing/unpacking added)
|
||
|
|
|
||
|
|
config.h (not automatically generated, sets memory sizes, enables/disables manual alloc)
|
||
|
|
user_misc.h (contains the manual memory alloc routines, with debug code to display mem usage)
|
||
|
|
speex\speex_config_types.h (match Speex types to compiler types, not generated from types.in)
|
||
|
|
|
||
|
|
speex_c54_test\speex_c54_test.cmd (C5416 linker command file)
|
||
|
|
speex_c54_test\speex_c54_test.pjt (Code Composer Studio Project File )
|
||
|
|
speex_c55_test\speex_c55_test.cmd (C5509A linker command file)
|
||
|
|
speex_c55_test\speex_c55_test.pjt (Code Composer Studio Project File )
|
||
|
|
speex_c64_test\speex_c64_test.cmd (C6415 linker command file)
|
||
|
|
speex_c64_test\speex_c64_test.pjt (Code Composer Studio Project File )
|
||
|
|
|
||
|
|
samples\male.snd
|
||
|
|
|
||
|
|
Usage:
|
||
|
|
1. Create a Speex 1.1.11 (or later) source tree.
|
||
|
|
2. Edit the files testenc-TI-C5x.c and/or testenc-TI-C64x.c to change the hard-coded path
|
||
|
|
for the test audio and data files.
|
||
|
|
This build uses the file e:\speextrunktest\samples\male.snd.
|
||
|
|
Note: This is a headerless 16-bit stereo audio file derived from the male.wav test file
|
||
|
|
http://www.speex.org/samples/male.wav
|
||
|
|
3. Edit the .pjt file with a text editor and change projdir or projectdir to the correct path
|
||
|
|
(one place near the top of the file).
|
||
|
|
4. Edit config.h if desired, to change the memory allocation method (calloc or manual),
|
||
|
|
and to enable/disable debug prints for the memory allocation
|
||
|
|
(this makes it easier to determine the required size).
|
||
|
|
5. Run Code Composer Studio, and open the project for the desired target (e.g. speex_c55_test).
|
||
|
|
Note that the correct simulator must be selected (in CCS Setup) before starting CCS.
|
||
|
|
6. Build and run the simulation.
|
||
|
|
|
||
|
|
Note that assembly optimizations will be required to run C54x in real time.
|
||
|
|
There are no assembly optimizations in any of these builds.
