+/**
+ \mainpage CMSIS DSP Software Library
+ *
+ * Introduction
+ *
+ * This user manual describes the CMSIS DSP software library,
+ * a suite of common signal processing functions for use on Cortex-M processor based devices.
+ *
+ * The library is divided into a number of modules each covering a specific category:
+ * - Basic math functions
+ * - Fast math functions
+ * - Complex math functions
+ * - Filters
+ * - Matrix functions
+ * - Transforms
+ * - Motor control functions
+ * - Statistical functions
+ * - Support functions
+ * - Interpolation functions
+ *
+ * The library has separate functions for operating on 8-bit integers, 16-bit integers,
+ * 32-bit integer and 32-bit floating-point values.
+ *
+ * Processor Support
+ *
+ * The library is completely written in C and is fully CMSIS compliant.
+ * High performance is achieved through maximum use of Cortex-M4 intrinsics.
+ *
+ * The supplied library source code also builds and runs on the Cortex-M3 and Cortex-M0 processor,
+ * with the DSP intrinsics being emulated through software.
+ *
+ *
+ * Toolchain Support
+ *
+ * The library has been developed and tested with MDK-ARM version 4.21.
+ * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly.
+ *
+ * Using the Library
+ *
+ * The library installer contains prebuilt versions of the libraries in the Lib folder.
+ * - arm_cortexM4lf_math.lib (Little endian and Floating Point Unit on Cortex-M4)
+ * - arm_cortexM4bf_math.lib (Big endian and Floating Point Unit on Cortex-M4)
+ * - arm_cortexM4l_math.lib (Little endian on Cortex-M4)
+ * - arm_cortexM4b_math.lib (Big endian on Cortex-M4)
+ * - arm_cortexM3l_math.lib (Little endian on Cortex-M3)
+ * - arm_cortexM3b_math.lib (Big endian on Cortex-M3)
+ * - arm_cortexM0l_math.lib (Little endian on Cortex-M0)
+ * - arm_cortexM0b_math.lib (Big endian on Cortex-M3)
+ *
+ * The library functions are declared in the public file arm_math.h which is placed in the Include folder.
+ * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
+ * public header file arm_math.h for Cortex-M4/M3/M0 with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
+ * Define the appropriate pre processor MACRO ARM_MATH_CM4 or ARM_MATH_CM3 or
+ * ARM_MATH_CM0 depending on the target processor in the application.
+ *
+ * Examples
+ *
+ * The library ships with a number of examples which demonstrate how to use the library functions.
+ *
+ * Building the Library
+ *
+ * The library installer contains project files to re build libraries on MDK Tool chain in the CMSIS\\DSP_Lib\\Source\\ARM folder.
+ * - arm_cortexM0b_math.uvproj
+ * - arm_cortexM0l_math.uvproj
+ * - arm_cortexM3b_math.uvproj
+ * - arm_cortexM3l_math.uvproj
+ * - arm_cortexM4b_math.uvproj
+ * - arm_cortexM4l_math.uvproj
+ * - arm_cortexM4bf_math.uvproj
+ * - arm_cortexM4lf_math.uvproj
+ *
+ * Each library project have differant pre-processor macros.
+ *
+ * ARM_MATH_CMx:
+ * Define macro ARM_MATH_CM4 for building the library on Cortex-M4 target, ARM_MATH_CM3 for building library on Cortex-M3 target
+ * and ARM_MATH_CM0 for building library on cortex-M0 target.
+ *
+ * ARM_MATH_BIG_ENDIAN:
+ * Define macro ARM_MATH_BIG_ENDIAN to build the library for big endian targets. By default library builds for little endian targets.
+ *
+ * ARM_MATH_MATRIX_CHECK:
+ * Define macro for checking on the input and output sizes of matrices
+ *
+ * ARM_MATH_ROUNDING:
+ * Define macro for rounding on support functions
+ *
+ * __FPU_PRESENT:
+ * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries
+ *
+ *
+ * The project can be built by opening the appropriate project in MDK-ARM 4.21 chain and defining the optional pre processor MACROs detailed above.

+
+/**
+ * @defgroup groupFastMath Fast Math Functions
+ * This set of functions provides a fast approximation to sine, cosine, and square root.
+ * As compared to most of the other functions in the CMSIS math library, the fast math functions
+ * operate on individual values and not arrays.
+ * There are separate functions for Q15, Q31, and floating-point data.
+ *
+ */
+
+/**
+ * @defgroup groupCmplxMath Complex Math Functions
+ * This set of functions operates on complex data vectors.
+ * The data in the complex arrays is stored in an interleaved fashion
+ * (real, imag, real, imag, ...).
+ * In the API functions, the number of samples in a complex array refers
+ * to the number of complex values; the array contains twice this number of
+ * real values.
+ */
+
+/**
+ * @defgroup groupFilters Filtering Functions
+ */
+
+/**
+ * @defgroup groupMatrix Matrix Functions
+ *
+ * This set of functions provides basic matrix math operations.
+ * The functions operate on matrix data structures. For example,
+ * the type
+ * definition for the floating-point matrix structure is shown
+ * below:
+ *
+ * typedef struct
+ * {
+ * uint16_t numRows; // number of rows of the matrix.
+ * uint16_t numCols; // number of columns of the matrix.
+ * float32_t *pData; // points to the data of the matrix.
+ * } arm_matrix_instance_f32;
+ *
+ * There are similar definitions for Q15 and Q31 data types.
+ *
+ * The structure specifies the size of the matrix and then points to
+ * an array of data. The array is of size numRows X numCols
+ * and the values are arranged in row order. That is, the
+ * matrix element (i, j) is stored at:
+ *
+ * pData[i*numCols + j]
+ *
+ *
+ * \par Init Functions
+ * There is an associated initialization function for each type of matrix
+ * data structure.
+ * The initialization function sets the values of the internal structure fields.
+ * Refer to the function arm_mat_init_f32(), arm_mat_init_q31()
+ * and arm_mat_init_q15() for floating-point, Q31 and Q15 types, respectively.
+ *
+ * \par
+ * Use of the initialization function is optional. However, if initialization function is used
+ * then the instance structure cannot be placed into a const data section.
+ * To place the instance structure in a const data
+ * section, manually initialize the data structure. For example:
+ *
+ * arm_matrix_instance_f32 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q31 S = {nRows, nColumns, pData};
+ * arm_matrix_instance_q15 S = {nRows, nColumns, pData};
+ *
+ * where nRows specifies the number of rows, nColumns
+ * specifies the number of columns, and pData points to the
+ * data array.
+ *
+ * \par Size Checking
+ * By default all of the matrix functions perform size checking on the input and
+ * output matrices. For example, the matrix addition function verifies that the
+ * two input matrices and the output matrix all have the same number of rows and
+ * columns. If the size check fails the functions return:
+ *
+ * ARM_MATH_SIZE_MISMATCH
+ *
+ * Otherwise the functions return
+ *
+ * ARM_MATH_SUCCESS
+ *
+ * There is some overhead associated with this matrix size checking.
+ * The matrix size checking is enabled via the \#define
+ *
+ * ARM_MATH_MATRIX_CHECK
+ *
+ * within the library project settings. By default this macro is defined
+ * and size checking is enabled. By changing the project settings and
+ * undefining this macro size checking is eliminated and the functions
+ * run a bit faster. With size checking disabled the functions always
+ * return ARM_MATH_SUCCESS.

+ *
+ * A Proportional Integral Derivative (PID) controller is a generic feedback control
+ * loop mechanism widely used in industrial control systems.
+ * A PID controller is the most commonly used type of feedback controller.
+ *
+ * This set of functions implements (PID) controllers
+ * for Q15, Q31, and floating-point data types. The functions operate on a single sample
+ * of data and each call to the function returns a single processed value.
+ * S points to an instance of the PID control data structure. in
+ * is the input sample value. The functions return the output value.
+ *
+ * \par Algorithm:
+ *
+ * y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
+ * A0 = Kp + Ki + Kd
+ * A1 = (-Kp ) - (2 * Kd )
+ * A2 = Kd
+ *
+ * \par
+ * where \c Kp is proportional constant, \c Ki is Integral constant and \c Kd is Derivative constant
+ *
+ * \par
+ * \image html PID.gif "Proportional Integral Derivative Controller"
+ *
+ * \par
+ * The PID controller calculates an "error" value as the difference between
+ * the measured output and the reference input.
+ * The controller attempts to minimize the error by adjusting the process control inputs.
+ * The proportional value determines the reaction to the current error,
+ * the integral value determines the reaction based on the sum of recent errors,
+ * and the derivative value determines the reaction based on the rate at which the error has been changing.
+ *
+ * \par Instance Structure
+ * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
+ * A separate instance structure must be defined for each PID Controller.
+ * There are separate instance structure declarations for each of the 3 supported data types.
+ *
+ * \par Reset Functions
+ * There is also an associated reset function for each data type which clears the state array.
+ *
+ * \par Initialization Functions
+ * There is also an associated initialization function for each data type.
+ * The initialization function performs the following operations:
+ * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
+ * - Zeros out the values in the state buffer.
+ *
+ * \par
+ * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
+ *
+ * \par Fixed-Point Behavior
+ * Care must be taken when using the fixed-point versions of the PID Controller functions.
+ * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
+ * Refer to the function specific documentation below for usage guidelines.

+ * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
+ *
+ * Algorithm
+ * \par
+ * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
+ * For floating-point, the instance structure is defined as:
+ *
+ * typedef struct
+ * {
+ * uint16_t numRows;
+ * uint16_t numCols;
+ * float32_t *pData;
+ * } arm_bilinear_interp_instance_f32;
+ *
+ *
+ * \par
+ * where numRows specifies the number of rows in the table;
+ * numCols specifies the number of columns in the table;
+ * and pData points to an array of size numRows*numCols values.
+ * The data table pTable is organized in row order and the supplied data values fall on integer indexes.
+ * That is, table element (x,y) is located at pTable[x + y*numCols] where x and y are integers.
+ *
+ * \par
+ * Let (x, y) specify the desired interpolation point. Then define:
+ *
+ * XF = floor(x)
+ * YF = floor(y)
+ *
+ * \par
+ * The interpolated output point is computed as:
+ *
+ * f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))
+ * + f(XF+1, YF) * (x-XF)*(1-(y-YF))
+ * + f(XF, YF+1) * (1-(x-XF))*(y-YF)
+ * + f(XF+1, YF+1) * (x-XF)*(y-YF)
+ *
+ * Note that the coordinates (x, y) contain integer and fractional components.
+ * The integer components specify which portion of the table to use while the
+ * fractional components control the interpolation processor.
+ *
+ * \par
+ * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.

+ *
+ * In addition to the standard demo tasks, the following tasks and tests are
+ * defined and/or created within this file:
+ *
+ * "Check" timer - The check software timer period is initially set to three
+ * seconds. The callback function associated with the check software timer
+ * checks that all the standard demo tasks are not only still executing, but
+ * are executing without reporting any errors. If the check software timer
+ * discovers that a task has either stalled, or reported an error, then it
+ * changes its own execution period from the initial three seconds, to just
+ * 200ms. The check software timer callback function also toggles an LED each
+ * time it is called. This provides a visual indication of the system status:
+ * If the LED toggles every three seconds, then no issues have been discovered.
+ * If the LED toggles every 200ms, then an issue has been discovered with at
+ * least one task.

+ * When configCREATE_LOW_POWER_DEMO is set to 1 in FreeRTOSConfig.h main() will
+ * call main_low_power(), which is defined in this file. main_low_power()
+ * demonstrates FreeRTOS tick suppression being used to allow the MCU to be
+ * placed into the Retention low power mode. When configCREATE_LOW_POWER_DEMO
+ * is set to 0 main will instead call main_full(), which is a more comprehensive
+ * RTOS demonstration.
+ * ****************************************************************************
+ *
+ * This application demonstrates the FreeRTOS tickless idle mode (tick
+ * suppression). See http://www.freertos.org/low-power-tickless-rtos.html
+ * The demo is configured to execute on the SAM4L-EK.
+ *
+ * Functionality:
+ *
+ * + Two tasks are created, an Rx task and a Tx task.
+ *
+ * + The Rx task blocks on a queue to wait for data, blipping an LED each time
+ * data is received (turning it on and then off again) before returning to
+ * block on the queue once more.
+ *
+ * + The Tx task repeatedly enters the Blocked state for 500ms. On exiting the
+ * blocked state the Tx task sends a value through the queue to the Rx task
+ * (causing the Rx task to exit the blocked state and blip the LED).
+ *
+ * Blocking for a finite period allows the kernel to stop the tick interrupt
+ * and place the SAM4L into Retention mode - the lowest power mode possible
+ * that allows the CPU registers and RAM to retain their state.
+ *
+ * Observed behaviour:
+ *
+ * For correct results the SAM4L-EK must be connected (and powered) using only
+ * the JTAG USB connector, but the debugger must not be connected (the
+ * application must be executed 'stand alone').
+ *
+ * The MCU spends most of its time in the Retention low power state, during
+ * which times the current monitor (built onto the SAM4L-EK) will show a low
+ * current reading.
+ *
+ * Every 500ms the MCU will come out of the low power state to turn the LED on,
+ * then return to the low power state for 20ms before leaving the low power
+ * state again to turn the LED off. This will be observed as a fast blipping
+ * on the LED, and two very brief dots appearing on the current monitor graph
+ * (often observed as a single dot).
+ *
+ * The RTOS tick is suppressed while the MCU is in its low power state.
