+ \mainpage CMSIS NN Software Library
+ *
+ * Introduction
+ * ------------
+ *
+ * This user manual describes the CMSIS NN software library,
+ * a collection of efficient neural network kernels developed to maximize the
+ * performance and minimize the memory footprint of neural networks on Cortex-M processor cores.
+ *
+ * The library is divided into a number of functions each covering a specific category:
+ * - Neural Network Convolution Functions
+ * - Neural Network Activation Functions
+ * - Fully-connected Layer Functions
+ * - Neural Network Pooling Functions
+ * - Softmax Functions
+ * - Neural Network Support Functions
+ *
+ * The library has separate functions for operating on different weight and activation data
+ * types including 8-bit integers (q7_t) and 16-bit integers (q15_t). The descrition of the
+ * kernels are included in the function description. The implementation details are also
+ * described in this paper [1].
+ *
+ * Block Diagram
+ * --------
+ * \image html CMSIS-NN-OVERVIEW.PNG
+ *
+ * Examples
+ * --------
+ *
+ * The library ships with a number of examples which demonstrate how to use the library functions.
+ *
+ * Pre-processor Macros
+ * ------------
+ *
+ * Each library project have differant pre-processor macros.
+ *
+ * - ARM_MATH_DSP:
+ *
+ * Define macro ARM_MATH_DSP, If the silicon supports DSP instructions.
+ *
+ * - 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_NN_TRUNCATE:
+ *
+ * Define macro ARM_NN_TRUNCATE to use floor instead of round-to-the-nearest-int for the computation.

+ * multiplication.
+ *
+ * To reduce the memory footprint, the im2col is performed partially.
