+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.

+/* To avoid changing the Speex call model, this file relies on four static variables 

+   The user main creates two linear buffers, and initializes spxGlobalHeap/ScratchPtr 

+   to point to the start of the two buffers, and initializes spxGlobalHeap/ScratchEnd 

+   to point to the first address following the last byte of the two buffers.

+   

+   This mechanism allows, for example, data caching for multichannel applications, 

+   where the Speex state is swapped from a large slow memory to a small fast memory 

+   each time the codec runs.

+   

+   Persistent data is allocated in spxGlobalHeap (instead of calloc), while scratch

+   data is allocated in spxGlobalScratch.
