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. |
