\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.

* Perform convolution layer
*
* The convolution is implemented in 2 steps: im2col and GEMM
*
* im2col is a process of converting each patch of image data into
* a column. After im2col, the convolution is computed as matrix-matrix
* multiplication.
*
* To reduce the memory footprint, the im2col is performed partially.
* Each iteration, only a few column (i.e., patches) are generated and
* computed with GEMM kernels similar to CMSIS-DSP arm_mat_mult functions.

* Perform fully-connected layer
*
* Fully-connected layer is basically a matrix-vector multiplication
* with bias. The matrix is the weights and the input/output vectors
* are the activation values. Supported {weight, activation} precisions
* include {8-bit, 8-bit}, {16-bit, 16-bit}, and {8-bit, 16-bit}.
*
* Here we have two types of kernel functions. The basic function
* implements the function using regular GEMV approach. The opt functions
* operates with weights in interleaved formats.
