The Library supports single * public header file <code> arm_math.h</code> 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 or ARM_MATH_CM0PLUS depending on the target processor in the application. * * <b>Examples</b> * * The library ships with a number of examples which demonstrate how to use the library functions. * * <b>Toolchain Support</b> * * The library has been developed and tested with MDK-ARM version 4.60. * The library is being tested in GCC and IAR toolchains and updates on this activity will be made available shortly. * * <b>Building the Library</b> * * The library installer contains project files to re build libraries on MDK Tool chain in the <code>CMSIS\\DSP_Lib\\Source\\ARM</code> 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 * * * The project can be built by opening the appropriate project in MDK-ARM 4.60 chain and defining the optional pre processor MACROs detailed above. * * <b>Pre-processor Macros</b> * * Each library project have differant pre-processor macros. * * - UNALIGNED_SUPPORT_DISABLE: * * Define macro UNALIGNED_SUPPORT_DISABLE, If the silicon does not support unaligned memory access * * - 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 ARM_MATH_MATRIX_CHECK for checking on the input and output sizes of matrices * * - ARM_MATH_ROUNDING: * * Define macro ARM_MATH_ROUNDING for rounding on support functions * * - 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_CM0PLUS for building library on cortex-M0+ target. * * - __FPU_PRESENT: * * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries * * <b>Copyright Notice</b> * * Copyright (C) 2010-2013 ARM Limited.

For example, * the type * definition for the floating-point matrix structure is shown * below: * <pre> * 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; * </pre> * 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 <code>numRows X numCols</code> * and the values are arranged in
