+ *
+ * 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
*
- * The library is completely written in C and is fully CMSIS compliant.
- * High performance is achieved through maximum use of Cortex-M4 intrinsics.
+ * - ARM_MATH_CMx:
*
- * The supplied library source code also builds and runs on the Cortex-M3 and Cortex-M0 processor,
- * with the DSP intrinsics being emulated through software.
+ * 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.
+ *
+ * - __FPU_PRESENT:
*
+ * Initialize macro __FPU_PRESENT = 1 when building on FPU supported Targets. Enable this macro for M4bf and M4lf libraries
