I. Description
|
|
|
|
This package contains files for compilation and evaluation of the fixed
|
|
point SILK SDK library. The following is included in this package:
|
|
|
|
o Source code for the fixed point SILK SDK library
|
|
o Source code for creating encoder and decoder executables
|
|
o Test vectors
|
|
o Comparison tool
|
|
o Microsoft Visual Studio solution and project files
|
|
o Makefile for GNU C-compiler (GCC)
|
|
|
|
II. Files and Folders
|
|
|
|
o doc/ - contains more information about the SILK SDK
|
|
o interface/ - contains API header files
|
|
o src/ - contains all SILK SDK library source files
|
|
o test/ - contains source files for testing the SILK SDK
|
|
o test_vectors/ - contains test vectors
|
|
o Makefile - Makefile for compiling with GCC
|
|
o readme.txt - this file
|
|
o Silk_SDK.sln - Visual Studio solution for all SILK SDK code
|
|
|
|
III. How to use the Makefile
|
|
|
|
1. How to clean and compile the SILK SDK library:
|
|
|
|
make clean lib
|
|
|
|
2. How to compile an encoder executable:
|
|
|
|
make encoder
|
|
|
|
3. How to compile a decoder executable:
|
|
|
|
make decoder
|
|
|
|
4. How to compile the comparison tool:
|
|
|
|
make signalcompare
|
|
|
|
5. How to clean and compile all of the above:
|
|
|
|
make clean all
|
|
|
|
6. How to build for big endian CPU's
|
|
|
|
Make clean all ADDED_DEFINES+=_SYSTEM_IS_BIG_ENDIAN
|
|
To be able to use the test vectors with big endian CPU's the test programs
|
|
need to be compiled in a different way. Note that the 16 bit input and output
|
|
from the test programs will have the upper and lower bytes swapped with this setting.
|
|
|
|
7. How to use the comparison tool:
|
|
|
|
See 'How to use the test vectors.txt' in the test_vectors folder.
|
|
|
