Kojto	123:b0220dba8be7	44	* Introduction
Kojto	123:b0220dba8be7	45	* ------------
Kojto	123:b0220dba8be7	46	*
Kojto	123:b0220dba8be7	47	* This user manual describes the CMSIS DSP software library,
Kojto	123:b0220dba8be7	48	* a suite of common signal processing functions for use on Cortex-M processor based devices.
Kojto	123:b0220dba8be7	49	*
Kojto	123:b0220dba8be7	50	* The library is divided into a number of functions each covering a specific category:
Kojto	123:b0220dba8be7	51	* - Basic math functions
Kojto	123:b0220dba8be7	52	* - Fast math functions
Kojto	123:b0220dba8be7	53	* - Complex math functions

Kojto	123:b0220dba8be7	61	*
Kojto	123:b0220dba8be7	62	* The library has separate functions for operating on 8-bit integers, 16-bit integers,
Kojto	123:b0220dba8be7	63	* 32-bit integer and 32-bit floating-point values.
Kojto	123:b0220dba8be7	64	*
Kojto	123:b0220dba8be7	65	* Using the Library
Kojto	123:b0220dba8be7	66	* ------------
Kojto	123:b0220dba8be7	67	*
Kojto	123:b0220dba8be7	68	* The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.

Kojto	123:b0220dba8be7	82	* - arm_cortexM0b_math.lib (Big endian on Cortex-M0 / CortexM0+)
Kojto	123:b0220dba8be7	83	*
Kojto	123:b0220dba8be7	84	* The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
Kojto	123:b0220dba8be7	85	* Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
Kojto	123:b0220dba8be7	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.
Kojto	123:b0220dba8be7	87	* Define the appropriate pre processor MACRO ARM_MATH_CM7 or ARM_MATH_CM4 or ARM_MATH_CM3 or
Kojto	123:b0220dba8be7	88	* ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.

Kojto	123:b0220dba8be7	195	* This set of functions provides basic matrix math operations.
Kojto	123:b0220dba8be7	196	* The functions operate on matrix data structures. For example,
Kojto	123:b0220dba8be7	197	* the type
Kojto	123:b0220dba8be7	198	* definition for the floating-point matrix structure is shown
Kojto	123:b0220dba8be7	199	* below:
Kojto	123:b0220dba8be7	200	* <pre>
Kojto	123:b0220dba8be7	201	* typedef struct
Kojto	123:b0220dba8be7	202	* {
Kojto	123:b0220dba8be7	203	* uint16_t numRows; // number of rows of the matrix.
Kojto	123:b0220dba8be7	204	* uint16_t numCols; // number of columns of the matrix.
Kojto	123:b0220dba8be7	205	* float32_t *pData; // points to the data of the matrix.
Kojto	123:b0220dba8be7	206	* } arm_matrix_instance_f32;
Kojto	123:b0220dba8be7	207	* </pre>
Kojto	123:b0220dba8be7	208	* There are similar definitions for Q15 and Q31 data types.
Kojto	123:b0220dba8be7	209	*
Kojto	123:b0220dba8be7	210	* The structure specifies the size of the matrix and then points to
Kojto	123:b0220dba8be7	211	* an array of data. The array is of size <code>numRows X numCols</code>
Kojto	123:b0220dba8be7	212	* and the values are arranged in row order. That is, the
Kojto	123:b0220dba8be7	213	* matrix element (i, j) is stored at:
Kojto	123:b0220dba8be7	214	* <pre>
Kojto	123:b0220dba8be7	215	* pData[i*numCols + j]
Kojto	123:b0220dba8be7	216	* </pre>
Kojto	123:b0220dba8be7	217	*
Kojto	123:b0220dba8be7	218	* \par Init Functions
Kojto	123:b0220dba8be7	219	* There is an associated initialization function for each type of matrix
Kojto	123:b0220dba8be7	220	* data structure.
Kojto	123:b0220dba8be7	221	* The initialization function sets the values of the internal structure fields.
Kojto	123:b0220dba8be7	222	* Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto	123:b0220dba8be7	223	* and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto	123:b0220dba8be7	224	*
Kojto	123:b0220dba8be7	225	* \par
Kojto	123:b0220dba8be7	226	* Use of the initialization function is optional. However, if initialization function is used
Kojto	123:b0220dba8be7	227	* then the instance structure cannot be placed into a const data section.
Kojto	123:b0220dba8be7	228	* To place the instance structure in a const data
Kojto	123:b0220dba8be7	229	* section, manually initialize the data structure. For example:
Kojto	123:b0220dba8be7	230	* <pre>
Kojto	123:b0220dba8be7	231	* <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto	123:b0220dba8be7	232	* <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto	123:b0220dba8be7	233	* <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto	123:b0220dba8be7	234	* </pre>
Kojto	123:b0220dba8be7	235	* where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto	123:b0220dba8be7	236	* specifies the number of columns, and <code>pData</code> points to the

Kojto	123:b0220dba8be7	243	* columns. If the size check fails the functions return:

Kojto	123:b0220dba8be7	5060	* the integral value determines the reaction based on the sum of recent errors,

Kojto	123:b0220dba8be7	5064	* The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
Kojto	123:b0220dba8be7	5065	* A separate instance structure must be defined for each PID Controller.
