+  */
+
+  this demo is based on the at-start board, in this demo(project_l0, step1 of
+  the slib example) describes how to generate an execute-only ip-code (using
+  compiler options), place and protect it (protection using slib) in some preferred
+  sectors in internal flash memory. the fir filter algorithm from cmsis library
+  is chosen as an example of ip-code to be protected. enabling slib is managed
+  by software in slib_enable() function.
+  
+  the ip-code function fir_lowpass_filter() is called in main.c file. note that
+  symbol definition file have to be generated in project configuration described
+  below, it has to be used in customer project project_l1.
+  
+  with the project configurations, the compiler is configured to generate an 
+  execute-only ip-code avoiding any data read from it (avoiding literal pools
+  and branch tables).
+  
+  @note the ip-code and ip-data are placed in sector 2 to sector 5 which will
+        be protected.
+  
+        activating the slib on these sectors is completed by slib_enable() function
+        descripes in main file.
+
+  @note the application needs to ensure that the systick time base is always
+        set to 1 millisecond to have correct operation.
+ 
+  @par Directory contents 
+  extra used files:
+  - project_l0/src/math_helper.c               calculation of snr 
+  - project_l0/src/arm_fir_data.c              contains fir_filter's input signal and reference output signal computed with matlab
+  - project_l0/inc/fir_filter.h                fir-filter slib protected ip-code header file
+
+  fir filter files representing the ip-code to be protected:
+  - project_l0/src/fir_filter.c                file containing global fir low pass filter function   
+  - project_l0/src/arm_fir_f32.c               file containing fir filter basic function from cmsis lib
+  - project_l0/src/arm_fir_init_f32.c          file containing fir filter initialization function from cmsis lib
+  - project_l0/src/fir_coefficient.c           file containing fir coefficients generated using fir1() matlab function.
+     
+  @par hardware and software environment  
+  - this example runs on at-start board.
+  - this example has been tested with the following toolchain:
+    keil mdk-arm uvision v5.18.0.0
+
+  @par generating symbol definition file 
+	generating symbol definition file is mandatory for project_l1 and the provided
+  file must be replaced by the newly generated.	to generate symbol definition
+  file required for project_l1, click on rebuild all button then symbol definition
+  file is created. 
+  - for mdk-arm toolchain: fir_filter_symbol.txt symbol definition file is created
+    in project_l0\mdk_v5\Objects. it must be modified by deleting all lines 
+    and keeping only fir-filter ip-code functions (please follow the provided 
+    fir_filter_symbol.txt file in project_l0\mdk_v5). once modified, copy it
+    to project_l1\mdk_v5 and replace the existing file.
+
+  @par how to use it ?   
+  before running this project the following conditions must be met:
+  - the same toolchain and compiler version must be used for both projects in
+    project_l0 and project_l1: for instance if mdk-arm v5.18 is used in project_l0
+    then it must be used for project_l1 too.
+  - check if any flash access protection(FAP), erase/program protection(EPP) 
+    or slib protection is enabled, if yes disable these protection first. 
+  
+  in order to make the program work, you must do the following :
+  
+  configurate the compiler to generate an execute only ip-code avoiding any 
+  data read from it (literal pools and branch tables) . 
+  1. open project located in project_l0 directory and choose your preferred toolchain 
+  2. select the project configuration
+  3. rebuild all files. 
+  4. run the example following the sequence below:
+     (a) power on the board then load the code, led3 should toggle fast if not
+         press reset button.
+     (b) press the user button key to execute the ip-code called in main.c file.
+     (c) if macro "use_slib_function" is defined and slib is never enabled, go
+         to step(e). 
+     (d) if the ip-code is successfully executed, the green led4 should toggle 
+         continuously. else the red led2 toggles continuously.  
+     (e) the slib_enable() function will set slib configuration once the ip-code
+         is correctly executed. the green led4 will turn on some time and then
+         a system rest is executed to activate slib. the code will run to step(b).
+
+  for details, please refer to the application note document AN0038.

+  @param[in] 	 numTaps    number of filter coefficients in the filter
+  @param[in]     pCoeffs    points to the filter coefficients buffer
+  @param[in]     pState     points to the state buffer
+  @param[in]     blockSize  number of samples processed per call
+  @return        none
+
+  @par           Details
+                   <code>pCoeffs</code> points to the array of filter coefficients stored in time reversed order:
+  <pre>
+      {b[numTaps-1], b[numTaps-2], b[N-2], ..., b[1], b[0]}
+  </pre>
+  @par
+                   <code>pState</code> points to the array of state variables.
+                   <code>pState</code> is of length <code>numTaps+blockSize-1</code> samples, where <code>blockSize</code> is the number of input samples processed by each call to <code>arm_fir_f32()</code>.
+  @par          Initialization of Helium version
+                 For Helium version the array of coefficients must be a multiple of 16 even if less
+                 then 16 coefficients are used. The additional coefficients must be set to 0.
+                 It does not mean that all the coefficients will be used in the filter (numTaps
+                 is still set to its right value in the init function.) It just means that
+                 the implementation may require to read more coefficients due to the vectorization and
+                 to avoid having to manage too many different cases in the code.

+  **************************************************************************
+  */
+
+  this demo is based on the at-start board, in this demo(project_l1, step2 of
+  the slib example), the mcu is already preloaded with fir-filter slib protected
+  ip-code (done in project_l0 project).
+  to call the ip-code fir_lowpass_filter() function:
+  - the fir_filter.h header file is included in main.c file
+  - symbol definition file (fir_filter_symbol.txt for mdk-arm) containing the
+    protected function symbols and addresses is included in this project. noting
+    that symbol definition file have to be generated in project_l0 in order to 
+    replace the existing one in this project.
+  
+  @note the application needs to ensure that the systick time base is always 
+  set to 1 millisecond to have correct operation.
+ 
+  @par directory contents 
+  extra used files:
+  - project_l1/src/math_helper.c               calculation of snr 
+  - project_l1/src/arm_fir_data.c              contains fir_filter's input signal and reference output signal computed with matlab
+
+  related ip-code files provided from project_l0:
+  - project_l1/mdk_v5/fir_filter_symbol.txt    symbol definition file for mdk-arm project containing slib protected code symbols and addresses
+  - project_l1/inc/fir_filter.h                fir-filter slib protected ip-code header file
+
+  @par hardware and software environment  
+  - this example runs on at-start board.
+  - this example has been tested with the following toolchain:
+    keil mdk-arm uvision v5.18.0.0
+
+  @par how to use it ? 
+  before running this project the following conditions must be met:
+  - the same toolchain and compiler version must be used for both projects in
+    project_l0 and project_l1: for instance if mdk-arm v5.18 is used in project_l0
+    then it must be used for project_l1 too.
+  - check if any flash access protection(FAP), erase/program protection(EPP) 
+    or slib protection is enabled, if yes disable these protection first. 
+
+  in order to make the program work, you must do the following :
+  
+  1. open project located in project_l1 directory and choose your preferred toolchain 
+  2. select the project configuration
+  3. rebuild all files. 
+  4. run the example following the sequence below:
+     (a) power on the board then load the code, led3 should toggle fast if not
+         press reset button.
+     (b) press the user button key to execute the ip-code called in main.c file.
+     (c) if the ip-code is successfully executed, the green led4 should toggle
+         continuously. else the red led2 toggles continuously.
+    
+  for details, please refer to the application note document AN0038.
