lypinator 0:bb348c97df44 34 *
lypinator 0:bb348c97df44 35 * This user manual describes the CMSIS DSP software library,
lypinator 0:bb348c97df44 36 * a suite of common signal processing functions for use on Cortex-M processor based devices.
lypinator 0:bb348c97df44 37 *
lypinator 0:bb348c97df44 38 * The library is divided into a number of functions each covering a specific category:
lypinator 0:bb348c97df44 39 * - Basic math functions
lypinator 0:bb348c97df44 40 * - Fast math functions
lypinator 0:bb348c97df44 41 * - Complex math functions
lypinator 0:bb348c97df44 42 * - Filters
lypinator 0:bb348c97df44 43 * - Matrix functions
lypinator 0:bb348c97df44 44 * - Transforms
lypinator 0:bb348c97df44 45 * - Motor control functions

lypinator 0:bb348c97df44 200 * This set of functions provides basic matrix math operations.
lypinator 0:bb348c97df44 201 * The functions operate on matrix data structures. For example,
lypinator 0:bb348c97df44 202 * the type
lypinator 0:bb348c97df44 203 * definition for the floating-point matrix structure is shown
lypinator 0:bb348c97df44 204 * below:
lypinator 0:bb348c97df44 205 * <pre>
lypinator 0:bb348c97df44 206 * typedef struct
lypinator 0:bb348c97df44 207 * {
lypinator 0:bb348c97df44 208 * uint16_t numRows; // number of rows of the matrix.
lypinator 0:bb348c97df44 209 * uint16_t numCols; // number of columns of the matrix.
lypinator 0:bb348c97df44 210 * float32_t *pData; // points to the data of the matrix.
lypinator 0:bb348c97df44 211 * } arm_matrix_instance_f32;
lypinator 0:bb348c97df44 212 * </pre>
lypinator 0:bb348c97df44 213 * There are similar definitions for Q15 and Q31 data types.
lypinator 0:bb348c97df44 214 *
lypinator 0:bb348c97df44 215 * The structure specifies the size of the matrix and then points to
lypinator 0:bb348c97df44 216 * an array of data. The array is of size <code>numRows X numCols</code>
lypinator 0:bb348c97df44 217 * and the values are arranged in row order. That is, the
lypinator 0:bb348c97df44 218 * matrix element (i, j) is stored at:
lypinator 0:bb348c97df44 219 * <pre>
lypinator 0:bb348c97df44 220 * pData[i*numCols + j]
lypinator 0:bb348c97df44 221 * </pre>
lypinator 0:bb348c97df44 222 *
lypinator 0:bb348c97df44 223 * \par Init Functions
lypinator 0:bb348c97df44 224 * There is an associated initialization function for each type of matrix
lypinator 0:bb348c97df44 225 * data structure.
lypinator 0:bb348c97df44 226 * The initialization function sets the values of the internal structure fields.
lypinator 0:bb348c97df44 227 * Refer to the function <code>arm_mat_init_f32()</code>, <code>arm_mat_init_q31()</code>
lypinator 0:bb348c97df44 228 * and <code>arm_mat_init_q15()</code> for floating-point, Q31 and Q15 types, respectively.
lypinator 0:bb348c97df44 229 *
lypinator 0:bb348c97df44 230 * \par
lypinator 0:bb348c97df44 231 * Use of the initialization function is optional. However, if initialization function is used
lypinator 0:bb348c97df44 232 * then the instance structure cannot be placed into a const data section.
lypinator 0:bb348c97df44 233 * To place the instance structure in a const data
lypinator 0:bb348c97df44 234 * section, manually initialize the data structure. For example:
lypinator 0:bb348c97df44 235 * <pre>
lypinator 0:bb348c97df44 236 * <code>arm_matrix_instance_f32 S = {nRows, nColumns, pData};</code>
lypinator 0:bb348c97df44 237 * <code>arm_matrix_instance_q31 S = {nRows, nColumns, pData};</code>
lypinator 0:bb348c97df44 238 * <code>arm_matrix_instance_q15 S = {nRows, nColumns, pData};</code>
lypinator 0:bb348c97df44 239 * </pre>
lypinator 0:bb348c97df44 240 * where <code>nRows</code> specifies the number of rows, <code>nColumns</code>
lypinator 0:bb348c97df44 241 * specifies the number of columns, and <code>pData</code> points to the
lypinator 0:bb348c97df44 242 * data array.
lypinator 0:bb348c97df44 243 *
lypinator 0:bb348c97df44 244 * \par Size Checking
lypinator 0:bb348c97df44 245 * By default all of the matrix functions perform size checking on the input and
lypinator 0:bb348c97df44 246 * output matrices. For example, the matrix addition function verifies that the
lypinator 0:bb348c97df44 247 * two input matrices and the output matrix all have the same number of rows and
lypinator 0:bb348c97df44 248 * columns. If the size check fails the functions return:

lypinator 0:bb348c97df44 4748 * This set of functions implements (PID) controllers
lypinator 0:bb348c97df44 4749 * for Q15, Q31, and floating-point data types. The functions operate on a single sample
lypinator 0:bb348c97df44 4750 * of data and each call to the function returns a single processed value.

lypinator 0:bb348c97df44 4768 * The PID controller calculates an "error" value as the difference between
lypinator 0:bb348c97df44 4769 * the measured output and the reference input.
lypinator 0:bb348c97df44 4770 * The controller attempts to minimize the error by adjusting the process control inputs.
lypinator 0:bb348c97df44 4771 * The proportional value determines the reaction to the current error,
lypinator 0:bb348c97df44 4772 * the integral value determines the reaction based on the sum of recent errors,
lypinator 0:bb348c97df44 4773 * and the derivative value determines the reaction based on the rate at which the error has been changing.
lypinator 0:bb348c97df44 4774 *
lypinator 0:bb348c97df44 4775 * \par Instance Structure
lypinator 0:bb348c97df44 4776 * The Gains A0, A1, A2 and state variables for a PID controller are stored together in an instance data structure.
lypinator 0:bb348c97df44 4777 * A separate instance structure must be defined for each PID Controller.
lypinator 0:bb348c97df44 4778 * There are separate instance structure declarations for each of the 3 supported data types.
lypinator 0:bb348c97df44 4779 *
lypinator 0:bb348c97df44 4780 * \par Reset Functions
lypinator 0:bb348c97df44 4781 * There is also an associated reset function for each data type which clears the state array.
lypinator 0:bb348c97df44 4782 *
lypinator 0:bb348c97df44 4783 * \par Initialization Functions
lypinator 0:bb348c97df44 4784 * There is also an associated initialization function for each data type.
lypinator 0:bb348c97df44 4785 * The initialization function performs the following operations:
lypinator 0:bb348c97df44 4786 * - Initializes the Gains A0, A1, A2 from Kp,Ki, Kd gains.
lypinator 0:bb348c97df44 4787 * - Zeros out the values in the state buffer.
lypinator 0:bb348c97df44 4788 *
lypinator 0:bb348c97df44 4789 * \par
lypinator 0:bb348c97df44 4790 * Instance structure cannot be placed into a const data section and it is recommended to use the initialization function.
lypinator 0:bb348c97df44 4791 *
lypinator 0:bb348c97df44 4792 * \par Fixed-Point Behavior
lypinator 0:bb348c97df44 4793 * Care must be taken when using the fixed-point versions of the PID Controller functions.
lypinator 0:bb348c97df44 4794 * In particular, the overflow and saturation behavior of the accumulator used in each function must be considered.

lypinator 0:bb348c97df44 6703 * Bilinear interpolation is an extension of linear interpolation applied to a two dimensional grid.
lypinator 0:bb348c97df44 6704 * The underlying function <code>f(x, y)</code> is sampled on a regular grid and the interpolation process
lypinator 0:bb348c97df44 6705 * determines values between the grid points.
lypinator 0:bb348c97df44 6706 * Bilinear interpolation is equivalent to two step linear interpolation, first in the x-dimension and then in the y-dimension.
lypinator 0:bb348c97df44 6707 * Bilinear interpolation is often used in image processing to rescale images.
lypinator 0:bb348c97df44 6708 * The CMSIS DSP library provides bilinear interpolation functions for Q7, Q15, Q31, and floating-point data types.
