Kojto 119:aae6fcc7d9bb 44 * Introduction
Kojto 119:aae6fcc7d9bb 45 * ------------
Kojto 119:aae6fcc7d9bb 46 *
Kojto 119:aae6fcc7d9bb 47 * This user manual describes the CMSIS DSP software library,
Kojto 119:aae6fcc7d9bb 48 * a suite of common signal processing functions for use on Cortex-M processor based devices.
Kojto 119:aae6fcc7d9bb 49 *
Kojto 119:aae6fcc7d9bb 50 * The library is divided into a number of functions each covering a specific category:
Kojto 119:aae6fcc7d9bb 51 * - Basic math functions
Kojto 119:aae6fcc7d9bb 52 * - Fast math functions
Kojto 119:aae6fcc7d9bb 53 * - Complex math functions
Kojto 119:aae6fcc7d9bb 54 * - Filters
Kojto 119:aae6fcc7d9bb 55 * - Matrix functions
Kojto 119:aae6fcc7d9bb 56 * - Transforms

Kojto 119:aae6fcc7d9bb 59 * - Support functions
Kojto 119:aae6fcc7d9bb 60 * - Interpolation functions
Kojto 119:aae6fcc7d9bb 61 *
Kojto 119:aae6fcc7d9bb 62 * The library has separate functions for operating on 8-bit integers, 16-bit integers,
Kojto 119:aae6fcc7d9bb 63 * 32-bit integer and 32-bit floating-point values.
Kojto 119:aae6fcc7d9bb 64 *
Kojto 119:aae6fcc7d9bb 65 * Using the Library
Kojto 119:aae6fcc7d9bb 66 * ------------
Kojto 119:aae6fcc7d9bb 67 *
Kojto 119:aae6fcc7d9bb 68 * The library installer contains prebuilt versions of the libraries in the <code>Lib</code> folder.
Kojto 119:aae6fcc7d9bb 69 * - arm_cortexM7lfdp_math.lib (Little endian and Double Precision Floating Point Unit on Cortex-M7)
Kojto 119:aae6fcc7d9bb 70 * - arm_cortexM7bfdp_math.lib (Big endian and Double Precision Floating Point Unit on Cortex-M7)

Kojto 119:aae6fcc7d9bb 83 *
Kojto 119:aae6fcc7d9bb 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 119:aae6fcc7d9bb 85 * Simply include this file and link the appropriate library in the application and begin calling the library functions. The Library supports single
Kojto 119:aae6fcc7d9bb 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 119:aae6fcc7d9bb 87 * Define the appropriate pre processor MACRO ARM_MATH_CM7 or ARM_MATH_CM4 or ARM_MATH_CM3 or
Kojto 119:aae6fcc7d9bb 88 * ARM_MATH_CM0 or ARM_MATH_CM0PLUS depending on the target processor in the application.
Kojto 119:aae6fcc7d9bb 89 *

Kojto 119:aae6fcc7d9bb 195 * This set of functions provides basic matrix math operations.
Kojto 119:aae6fcc7d9bb 196 * The functions operate on matrix data structures. For example,
Kojto 119:aae6fcc7d9bb 197 * the type
Kojto 119:aae6fcc7d9bb 198 * definition for the floating-point matrix structure is shown
Kojto 119:aae6fcc7d9bb 199 * below:
Kojto 119:aae6fcc7d9bb 200 * <pre>
Kojto 119:aae6fcc7d9bb 201 * typedef struct
Kojto 119:aae6fcc7d9bb 202 * {
Kojto 119:aae6fcc7d9bb 203 * uint16_t numRows; // number of rows of the matrix.
Kojto 119:aae6fcc7d9bb 204 * uint16_t numCols; // number of columns of the matrix.
Kojto 119:aae6fcc7d9bb 205 * float32_t *pData; // points to the data of the matrix.
Kojto 119:aae6fcc7d9bb 206 * } arm_matrix_instance_f32;
Kojto 119:aae6fcc7d9bb 207 * </pre>
Kojto 119:aae6fcc7d9bb 208 * There are similar definitions for Q15 and Q31 data types.
Kojto 119:aae6fcc7d9bb 209 *
Kojto 119:aae6fcc7d9bb 210 * The structure specifies the size of the matrix and then points to
Kojto 119:aae6fcc7d9bb 211 * an array of data. The array is of size <code>numRows X numCols</code>
Kojto 119:aae6fcc7d9bb 212 * and the values are arranged in row order. That is, the
Kojto 119:aae6fcc7d9bb 213 * matrix element (i, j) is stored at:
Kojto 119:aae6fcc7d9bb 214 * <pre>
Kojto 119:aae6fcc7d9bb 215 * pData[i*numCols + j]
Kojto 119:aae6fcc7d9bb 216 * </pre>
Kojto 119:aae6fcc7d9bb 217 *
Kojto 119:aae6fcc7d9bb 218 * \par Init Functions
Kojto 119:aae6fcc7d9bb 219 * There is an associated initialization function for each type of matrix
Kojto 119:aae6fcc7d9bb 220 * data structure.
Kojto 119:aae6fcc7d9bb 221 * The initialization function sets the values of the internal structure fields.
Kojto 119:aae6fcc7d9bb 222 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
Kojto 119:aae6fcc7d9bb 223 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
Kojto 119:aae6fcc7d9bb 224 *
Kojto 119:aae6fcc7d9bb 225 * \par
Kojto 119:aae6fcc7d9bb 226 * Use of the initialization function is optional. However, if initialization function is used
Kojto 119:aae6fcc7d9bb 227 * then the instance structure cannot be placed into a const data section.
Kojto 119:aae6fcc7d9bb 228 * To place the instance structure in a const data
Kojto 119:aae6fcc7d9bb 229 * section, manually initialize the data structure. For example:
Kojto 119:aae6fcc7d9bb 230 * <pre>
Kojto 119:aae6fcc7d9bb 231 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
Kojto 119:aae6fcc7d9bb 232 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
Kojto 119:aae6fcc7d9bb 233 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
Kojto 119:aae6fcc7d9bb 234 * </pre>
Kojto 119:aae6fcc7d9bb 235 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
Kojto 119:aae6fcc7d9bb 236 * specifies the number of columns, and <code>pData</code> points to the
Kojto 119:aae6fcc7d9bb 237 * data array.
Kojto 119:aae6fcc7d9bb 238 *
Kojto 119:aae6fcc7d9bb 239 * \par Size Checking
Kojto 119:aae6fcc7d9bb 240 * By default all of the matrix functions perform size checking on the input and
Kojto 119:aae6fcc7d9bb 241 * output matrices. For example, the matrix addition function verifies that the
Kojto 119:aae6fcc7d9bb 242 * two input matrices and the output matrix all have the same number of rows and
Kojto 119:aae6fcc7d9bb 243 * columns. If the size check fails the functions return:
Kojto 119:aae6fcc7d9bb 244 * <pre>
Kojto 119:aae6fcc7d9bb 245 * ARM_MATH_SIZE_MISMATCH
Kojto 119:aae6fcc7d9bb 246 * </pre>

Kojto 119:aae6fcc7d9bb 5032 * A Proportional Integral Derivative (PID) controller is a generic feedback control
Kojto 119:aae6fcc7d9bb 5033 * loop mechanism widely used in industrial control systems.
Kojto 119:aae6fcc7d9bb 5034 * A PID controller is the most commonly used type of feedback controller.
Kojto 119:aae6fcc7d9bb 5035 *
Kojto 119:aae6fcc7d9bb 5036 * This set of functions implements (PID) controllers
Kojto 119:aae6fcc7d9bb 5037 * for Q15, Q31, and floating-point data types. The functions operate on a single sample
Kojto 119:aae6fcc7d9bb 5038 * of data and each call to the function returns a single processed value.
Kojto 119:aae6fcc7d9bb 5039 * <code>S</code> points to an instance of the PID control data structure. <code>in</code>
Kojto 119:aae6fcc7d9bb 5040 * is the input sample value. The functions return the output value.
Kojto 119:aae6fcc7d9bb 5041 *
Kojto 119:aae6fcc7d9bb 5042 * \par Algorithm:
Kojto 119:aae6fcc7d9bb 5043 * <pre>
Kojto 119:aae6fcc7d9bb 5044 * y[n] = y[n-1] + A0 * x[n] + A1 * x[n-1] + A2 * x[n-2]
Kojto 119:aae6fcc7d9bb 5045 * A0 = Kp + Ki + Kd

Kojto 119:aae6fcc7d9bb 5056 * The PID controller calculates an "error" value as the difference between
Kojto 119:aae6fcc7d9bb 5057 * the measured output and the reference input.
Kojto 119:aae6fcc7d9bb 5058 * The controller attempts to minimize the error by adjusting the process control inputs.
Kojto 119:aae6fcc7d9bb 5059 * The proportional value determines the reaction to the current error,
Kojto 119:aae6fcc7d9bb 5060 * the integral value determines the reaction based on the sum of recent errors,
Kojto 119:aae6fcc7d9bb 5061 * and the derivative value determines the reaction based on the rate at which the error has been changing.
Kojto 119:aae6fcc7d9bb 5062 *
Kojto 119:aae6fcc7d9bb 5063 * \par Instance Structure
Kojto 119:aae6fcc7d9bb 5064 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
Kojto 119:aae6fcc7d9bb 5065 * A separate instance structure must be defined for each PID Controller.
Kojto 119:aae6fcc7d9bb 5066 * There are separate instance structure declarations for each of the 3 supported data types.
Kojto 119:aae6fcc7d9bb 5067 *
Kojto 119:aae6fcc7d9bb 5068 * \par Reset Functions
Kojto 119:aae6fcc7d9bb 5069 * There is also an associated reset function for each data type which clears the state array.
Kojto 119:aae6fcc7d9bb 5070 *
Kojto 119:aae6fcc7d9bb 5071 * \par Initialization Functions
Kojto 119:aae6fcc7d9bb 5072 * There is also an associated initialization function for each data type.
Kojto 119:aae6fcc7d9bb 5073 * The initialization function performs the following operations:
Kojto 119:aae6fcc7d9bb 5074 * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
Kojto 119:aae6fcc7d9bb 5075 * - Zeros out the values in the state buffer.
Kojto 119:aae6fcc7d9bb 5076 *
Kojto 119:aae6fcc7d9bb 5077 * \par
Kojto 119:aae6fcc7d9bb 5078 * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
Kojto 119:aae6fcc7d9bb 5079 *
Kojto 119:aae6fcc7d9bb 5080 * \par Fixed-Point Behavior
Kojto 119:aae6fcc7d9bb 5081 * Care must be taken when using the fixed-point versions of the PID Controller functions.
Kojto 119:aae6fcc7d9bb 5082 * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.
Kojto 119:aae6fcc7d9bb 5083 * Refer to the function specific documentation below for usage guidelines.

Kojto 119:aae6fcc7d9bb 7085 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
Kojto 119:aae6fcc7d9bb 7086 * determines values between the grid points.
Kojto 119:aae6fcc7d9bb 7087 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
Kojto 119:aae6fcc7d9bb 7088 * Bilinear interpolation is often used in image processing to rescale images.
Kojto 119:aae6fcc7d9bb 7089 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.

Kojto 119:aae6fcc7d9bb 7093 * The instance structure used by the bilinear interpolation functions describes a two dimensional data table.
Kojto 119:aae6fcc7d9bb 7094 * For floating-point, the instance structure is defined as:
Kojto 119:aae6fcc7d9bb 7095 * <pre>
Kojto 119:aae6fcc7d9bb 7096 * typedef struct
Kojto 119:aae6fcc7d9bb 7097 * {

Kojto 119:aae6fcc7d9bb 7104 * \par
Kojto 119:aae6fcc7d9bb 7105 * where <code>numRows</code> specifies the number of rows in the table;
Kojto 119:aae6fcc7d9bb 7106 * <code>numCols</code> specifies the number of columns in the table;
Kojto 119:aae6fcc7d9bb 7107 * and <code>pData</code> points to an array of size <code>numRows*numCols</code> values.
Kojto 119:aae6fcc7d9bb 7108 * The data table <code>pTable</code> is organized in row order and the supplied data values fall on integer indexes.
Kojto 119:aae6fcc7d9bb 7109 * That is, table element (x,y) is located at <code>pTable[x + y*numCols]</code> where x and y are integers.
Kojto 119:aae6fcc7d9bb 7110 *
Kojto 119:aae6fcc7d9bb 7111 * \par
Kojto 119:aae6fcc7d9bb 7112 * Let <code>(x, y)</code> specify the desired interpolation point. Then define:
Kojto 119:aae6fcc7d9bb 7113 * <pre>
Kojto 119:aae6fcc7d9bb 7114 * XF = floor(x)
Kojto 119:aae6fcc7d9bb 7115 * YF = floor(y)
Kojto 119:aae6fcc7d9bb 7116 * </pre>
Kojto 119:aae6fcc7d9bb 7117 * \par
Kojto 119:aae6fcc7d9bb 7118 * The interpolated output point is computed as:
Kojto 119:aae6fcc7d9bb 7119 * <pre>
Kojto 119:aae6fcc7d9bb 7120 * f(x, y) = f(XF, YF) * (1-(x-XF)) * (1-(y-YF))

Kojto 119:aae6fcc7d9bb 7122 * + f(XF, YF+1) * (1-(x-XF))*(y-YF)
Kojto 119:aae6fcc7d9bb 7123 * + f(XF+1, YF+1) * (x-XF)*(y-YF)
Kojto 119:aae6fcc7d9bb 7124 * </pre>
Kojto 119:aae6fcc7d9bb 7125 * Note that the coordinates (x, y) contain integer and fractional components.
Kojto 119:aae6fcc7d9bb 7126 * The integer components specify which portion of the table to use while the
Kojto 119:aae6fcc7d9bb 7127 * fractional components control the interpolation processor.
Kojto 119:aae6fcc7d9bb 7128 *
Kojto 119:aae6fcc7d9bb 7129 * \par
Kojto 119:aae6fcc7d9bb 7130 * if (x,y) are outside of the table boundary, Bilinear interpolation returns zero output.
