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.

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. - */ - -/** - * @ingroup DSP_Functions - * @defgroup groupTransforms Transform Functions - */ - -/** - * @ingroup DSP_Functions - * @defgroup groupController Controller Functions - */ - -/** - * @ingroup DSP_Functions - * @defgroup groupStats Statistics Functions - */ - -/** - * @ingroup DSP_Functions - * @defgroup groupSupport Support Functions - */ - -/** - * @ingroup DSP_Functions - * @defgroup groupInterpolation Interpolation Functions - * These functions perform 1- and 2-dimensional interpolation of data. - * Linear interpolation is used for 1-dimensional data and - * bilinear interpolation is used for 2-dimensional data. - */ - -/** - * @ingroup DSP_Lib - * @defgroup groupExamples Examples - */ -#ifndef _ARM_MATH_H -#define _ARM_MATH_H - -#define __CMSIS_GENERIC /* disable NVIC and Systick functions */ - -#if defined (ARM_MATH_CM4) - #include "core_cm4.h" -#elif defined (ARM_MATH_CM3) - #include "core_cm3.h" -#elif defined (ARM_MATH_CM0) - #include "core_cm0.h" -#else -#include "ARMCM4.h" -#warning "Define either ARM_MATH_CM4 OR ARM_MATH_CM3...By Default building on ARM_MATH_CM4....." -#endif - -#undef __CMSIS_GENERIC /* enable NVIC and Systick functions */ -#include "string.h" - #include "math.h" -#ifdef __cplusplus -extern "C" -{ -#endif - - - /** - * @brief Macros required for reciprocal calculation in Normalized LMS - */ - -#define DELTA_Q31 (0x100) -#define DELTA_Q15 0x5 -#define INDEX_MASK 0x0000003F -#define PI 3.14159265358979f - - /** - * @brief Macros required for SINE and COSINE Fast math approximations - */ - -#define TABLE_SIZE 256 -#define TABLE_SPACING_Q31 0x800000 -#define TABLE_SPACING_Q15 0x80 - - /** - * @brief Macros required for SINE and COSINE Controller functions - */ - /* 1.31(q31) Fixed value of 2/360 */ - /* -1 to +1 is divided into 360 values so total spacing is (2/360) */ -#define INPUT_SPACING 0xB60B61 - - - /** - * @brief Error status returned by some functions in the library. - */ - - typedef enum - { - ARM_MATH_SUCCESS = 0, /**< No error */ - ARM_MATH_ARGUMENT_ERROR = -1, /**< One or more arguments are incorrect */ - ARM_MATH_LENGTH_ERROR = -2, /**< Length of data buffer is incorrect */ - ARM_MATH_SIZE_MISMATCH = -3, /**< Size of matrices is not compatible with the operation. */ - ARM_MATH_NANINF = -4, /**< Not-a-number (NaN) or infinity is generated */ - ARM_MATH_SINGULAR = -5, /**< Generated by matrix inversion if the input matrix is singular and cannot be inverted. */ - ARM_MATH_TEST_FAILURE = -6 /**< Test Failed */ - } arm_status;
