- * @brief Fast Q7 version of 1x1 convolution (non-sqaure shape)
- * @param[in] Im_in pointer to input tensor
- * @param[in] dim_im_in_x input tensor dimention x
- * @param[in] dim_im_in_y input tensor dimention y
- * @param[in] ch_im_in number of input tensor channels
- * @param[in] wt pointer to kernel weights
- * @param[in] ch_im_out number of filters, i.e., output tensor channels
- * @param[in] dim_kernel_x filter kernel size x
- * @param[in] dim_kernel_y filter kernel size y
- * @param[in] padding_x padding size x
- * @param[in] padding_y padding size y
- * @param[in] stride_x convolution stride x
- * @param[in] stride_y convolution stride y
- * @param[in] bias pointer to bias
- * @param[in] bias_shift amount of left-shift for bias
- * @param[in] out_shift amount of right-shift for output
- * @param[in,out] Im_out pointer to output tensor
- * @param[in] dim_im_out_x output tensor dimension x
- * @param[in] dim_im_out_y output tensor dimension y
- * @param[in,out] bufferA pointer to buffer space for input
- * @param[in,out] bufferB pointer to buffer space for output
- * @return The function returns either
- * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
- *
- * This function is optimized for convolution with 1x1 kernel size (i.e., dim_kernel_x=1
- * and dim_kernel_y=1). It can be used for the second half of MobileNets [1] after depthwise
- * separable convolution.
- *
- * This function is the version with full list of optimization tricks, but with
- * some contraints:
- * ch_im_in is multiple of 4
- * ch_im_out is multiple of 2

- *
- * The im2col converts the Q7 tensor input into Q15 column, which is stored in
- * bufferA. There is reordering happenning during this im2col process with
- * arm_q7_to_q15_reordered_no_shift. For every four elements, the second and
- * third elements are swapped.
- *
- * The computation kernel arm_nn_mat_mult_kernel_q7_q15_reordered does the
- * GEMM computation with the reordered columns.
- *
- * To speed-up the determination of the padding condition, we split the
- * computation into 3x3 parts, i.e., {top, mid, bottom} X {left, mid, right}.
- * This reduces the total number of boundary condition checks and improves
- * the data copying performance.

- * @param[in] stride_y convolution stride y
- * @param[in] bias pointer to bias
- * @param[in] bias_shift amount of left-shift for bias

- * This function is the version with full list of optimization tricks, but with

- * @brief Q7 depthwise separable convolution function
- * @param[in] Im_in pointer to input tensor
- * @param[in] dim_im_in input tensor dimention
- * @param[in] ch_im_in number of input tensor channels
- * @param[in] wt pointer to kernel weights
- * @param[in] ch_im_out number of filters, i.e., output tensor channels
- * @param[in] dim_kernel filter kernel size
- * @param[in] padding padding sizes
- * @param[in] stride convolution stride
- * @param[in] bias pointer to bias
- * @param[in] bias_shift amount of left-shift for bias
- * @param[in] out_shift amount of right-shift for output
- * @param[in,out] Im_out pointer to output tensor
- * @param[in] dim_im_out output tensor dimension
- * @param[in,out] bufferA pointer to buffer space for input
- * @param[in,out] bufferB pointer to buffer space for output
- * @return The function returns either
- * <code>ARM_MATH_SIZE_MISMATCH</code> or <code>ARM_MATH_SUCCESS</code> based on the outcome of size checking.
- *
- * @details
- *
- * <b>Buffer size:</b>
- *
- * bufferA size: 2*ch_im_in*dim_kernel*dim_kernel
- *
- * bufferB size: 0
- *
- * <b>Input dimension constraints:</b>
- *
- * ch_im_in equals ch_im_out
- *
- * Implementation:
- * There are 3 nested loop here:
- * Inner loop: calculate each output value with MAC instruction over an accumulator
- * Mid loop: loop over different output channel
- * Outer loop: loop over different output (x, y)
