vipinranka	12:9a20164dcc47	44	* Introduction
vipinranka	12:9a20164dcc47	45	* ------------
vipinranka	12:9a20164dcc47	46	*
vipinranka	12:9a20164dcc47	47	* This user manual describes the CMSIS DSP software library,
vipinranka	12:9a20164dcc47	48	* a suite of common signal processing functions for use on Cortex-M processor based devices.
vipinranka	12:9a20164dcc47	49	*
vipinranka	12:9a20164dcc47	50	* The library is divided into a number of functions each covering a specific category:

vipinranka	12:9a20164dcc47	61	*
vipinranka	12:9a20164dcc47	62	* The library has separate functions for operating on 8-bit integers, 16-bit integers,
vipinranka	12:9a20164dcc47	63	* 32-bit integer and 32-bit floating-point values.
vipinranka	12:9a20164dcc47	64	*
vipinranka	12:9a20164dcc47	65	* Using the Library
vipinranka	12:9a20164dcc47	66	* ------------
vipinranka	12:9a20164dcc47	67	*
vipinranka	12:9a20164dcc47	68	* The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.

vipinranka	12:9a20164dcc47	82	* - arm_cortexM0b_math.lib (Big endian on Cortex-M0 / CortexM0+)
vipinranka	12:9a20164dcc47	83	*
vipinranka	12:9a20164dcc47	84	* The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
vipinranka	12:9a20164dcc47	85	* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
vipinranka	12:9a20164dcc47	86	* public header file <code> arm_math.h</code> for Cortex-M7/M4/M3/M0/M0+ with little endian and big endian. Same header file will be used for floating point unit(FPU) variants.
vipinranka	12:9a20164dcc47	87	* Define the appropriate pre processor MACRO ARM_MATH_CM7 or ARM_MATH_CM4 or ARM_MATH_CM3 or
vipinranka	12:9a20164dcc47	88	* ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.

vipinranka	12:9a20164dcc47	228	* To place the instance structure in a const data
vipinranka	12:9a20164dcc47	229	* section, manually initialize the data structure. For example:
vipinranka	12:9a20164dcc47	230	* <pre>
vipinranka	12:9a20164dcc47	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
vipinranka	12:9a20164dcc47	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
vipinranka	12:9a20164dcc47	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
vipinranka	12:9a20164dcc47	234	* </pre>
vipinranka	12:9a20164dcc47	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
vipinranka	12:9a20164dcc47	236	* specifies the number of columns, and <code>pData</code> points to the
vipinranka	12:9a20164dcc47	237	* data array.
vipinranka	12:9a20164dcc47	238	*
vipinranka	12:9a20164dcc47	239	* \par Size Checking
vipinranka	12:9a20164dcc47	240	* By default all of the matrix functions perform size checking on the input and
vipinranka	12:9a20164dcc47	241	* output matrices. For example, the matrix addition function verifies that the
vipinranka	12:9a20164dcc47	242	* two input matrices and the output matrix all have the same number of rows and
vipinranka	12:9a20164dcc47	243	* columns. If the size check fails the functions return:
vipinranka	12:9a20164dcc47	244	* <pre>
vipinranka	12:9a20164dcc47	245	* ARM_MATH_SIZE_MISMATCH
vipinranka	12:9a20164dcc47	246	* </pre>
vipinranka	12:9a20164dcc47	247	* Otherwise the functions return
vipinranka	12:9a20164dcc47	248	* <pre>
vipinranka	12:9a20164dcc47	249	* ARM_MATH_SUCCESS
vipinranka	12:9a20164dcc47	250	* </pre>
vipinranka	12:9a20164dcc47	251	* There is some overhead associated with this matrix size checking.
vipinranka	12:9a20164dcc47	252	* The matrix size checking is enabled via the \#define
vipinranka	12:9a20164dcc47	253	* <pre>
vipinranka	12:9a20164dcc47	254	* ARM_MATH_MATRIX_CHECK
vipinranka	12:9a20164dcc47	255	* </pre>
vipinranka	12:9a20164dcc47	256	* within the library project settings. By default this macro is defined
vipinranka	12:9a20164dcc47	257	* and size checking is enabled. By changing the project settings and
vipinranka	12:9a20164dcc47	258	* undefining this macro size checking is eliminated and the functions
vipinranka	12:9a20164dcc47	259	* run a bit faster. With size checking disabled the functions always
vipinranka	12:9a20164dcc47	260	* return <code>ARM_MATH_SUCCESS</code>.

vipinranka	12:9a20164dcc47	5057	* the measured output and the reference input.
vipinranka	12:9a20164dcc47	5058	* The controller attempts to minimize the error by adjusting the process control inputs.

vipinranka	12:9a20164dcc47	5060	* the integral value determines the reaction based on the sum of recent errors,

vipinranka	12:9a20164dcc47	5064	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
vipinranka	12:9a20164dcc47	5065	* A separate instance structure must be defined for each PID Controller.
vipinranka	12:9a20164dcc47	5066	* There are separate instance structure declarations for each of the 3 supported data types.

vipinranka	12:9a20164dcc47	5068	* \par Reset Functions
vipinranka	12:9a20164dcc47	5069	* There is also an associated reset function for each data type which clears the state array.
vipinranka	12:9a20164dcc47	5070	*
vipinranka	12:9a20164dcc47	5071	* \par Initialization Functions
vipinranka	12:9a20164dcc47	5072	* There is also an associated initialization function for each data type.
vipinranka	12:9a20164dcc47	5073	* The initialization function performs the following operations:
vipinranka	12:9a20164dcc47	5074	* - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
vipinranka	12:9a20164dcc47	5075	* - Zeros out the values in the state buffer.
vipinranka	12:9a20164dcc47	5076	*

vipinranka	12:9a20164dcc47	5078	* Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.

vipinranka	12:9a20164dcc47	5080	* \par Fixed-Point Behavior
vipinranka	12:9a20164dcc47	5081	* Care must be taken when using the fixed-point versions of the PID Controller functions.
vipinranka	12:9a20164dcc47	5082	* In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
vipinranka	12:9a20164dcc47	5083	* Refer to the function specific documentation below for usage guidelines.

vipinranka	12:9a20164dcc47	7084	* Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
vipinranka	12:9a20164dcc47	7085	* The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
vipinranka	12:9a20164dcc47	7086	* determines values between the grid points.
vipinranka	12:9a20164dcc47	7087	* Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
vipinranka	12:9a20164dcc47	7088	* Bilinear interpolation is often used in image processing to rescale images.
vipinranka	12:9a20164dcc47	7089	* The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
