- \mainpage CMSIS DSP Software Library
- *
- * \section intro Introduction
- *
- * This user manual describes the CMSIS DSP software library,
- * a suite of common signal processing functions for use on Cortex-M and Cortex-A processor
- * based devices.
- *
- * The library is divided into a number of functions each covering a specific category:
- * - Basic math functions
- * - Fast math functions
- * - Complex math functions
- * - Filtering functions
- * - Matrix functions
- * - Transform functions
- * - Motor control functions
- * - Statistical functions
- * - Support functions
- * - Interpolation functions
- * - Support Vector Machine functions (SVM)
- * - Bayes classifier functions
- * - Distance functions
- * - Quaternion functions
- *
- * The library has generally separate functions for operating on 8-bit integers, 16-bit integers,
- * 32-bit integer and 32-bit floating-point values.
- *
- * The library is providing vectorized versions of most algorthms for Helium
- * and of most f32 algorithms for Neon.
- *
- * When using a vectorized version, provide a little bit of padding after the end of
- * a buffer (3 words) because the vectorized code may read a little bit after the end
- * of a buffer. You don't have to modify your buffers but just ensure that the
- * end of buffer + padding is not outside of a memory region.
- *
- * \section using Using the Library
- *
- * The library is released in source form. It is strongly advised to compile the library using -Ofast to
- * have the best performances.
- *
- * The library functions are declared in the public file <code>arm_math.h</code> which is placed in the <code>Include</code> folder.
- * Simply include this file. If you don't want to include everything, you can also rely
- * on headers in Include/dsp folder and use only what you need.
- *
- * \section example Examples
- *
- * The library ships with a number of examples which demonstrate how to use the library functions.
- *
- * \section toolchain Toolchain Support
- *
- * The library is now tested on Fast Models building with cmake.
- * Core M0, M4, M7, M33, M55, A32 are tested.
- *
- *
- * \section preprocessor Preprocessor Macros
- *
- * Each library project have different preprocessor macros.
- *
- * - 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_LOOPUNROLL:
- *
- * Define macro ARM_MATH_LOOPUNROLL to enable manual loop unrolling in DSP functions
- *
- * - ARM_MATH_NEON:
- *
- * Define macro ARM_MATH_NEON to enable Neon versions of the DSP functions.
- * It is not enabled by default when Neon is available because performances are
- * dependent on the compiler and target architecture.
- *
- * - ARM_MATH_NEON_EXPERIMENTAL:
- *
- * Define macro ARM_MATH_NEON_EXPERIMENTAL to enable experimental Neon versions of
- * of some DSP functions. Experimental Neon versions currently do not have better
- * performances than the scalar versions.
- *
- * - ARM_MATH_HELIUM:
- *
- * It implies the flags ARM_MATH_MVEF and ARM_MATH_MVEI and ARM_MATH_MVE_FLOAT16.
- *
- * - ARM_MATH_HELIUM_EXPERIMENTAL:
- *
- * Only taken into account when ARM_MATH_MVEF, ARM_MATH_MVEI or ARM_MATH_MVE_FLOAT16 are defined.
- * Enable some vector versions which may have worse performance than scalar
- * depending on the core / compiler configuration.
- *
- * - ARM_MATH_MVEF:
- *
- * Select Helium versions of the f32 algorithms.
- * It implies ARM_MATH_FLOAT16 and ARM_MATH_MVEI.
- *
- * - ARM_MATH_MVEI:
- *
- * Select Helium versions of the int and fixed point algorithms.
- *
- * - ARM_MATH_MVE_FLOAT16:
- *
- * MVE Float16 implementations of some algorithms (Requires MVE extension).
- *
- * - DISABLEFLOAT16:
- *
- * Disable float16 algorithms when __fp16 is not supported for a
- * specific compiler / core configuration.
- * This is only valid for scalar. When vector architecture is
- * supporting f16 then it can't be disabled.
- *
- * - ARM_MATH_AUTOVECTORIZE:
- *
- * With Helium or Neon, disable the use of vectorized code with C intrinsics
- * and use pure C instead. The vectorization is then done by the compiler.
- *
