+ * @brief   add two arrays with paddings (add two sub-matrices)
+ *
+ * The function adds two arrays defined as sub-matrices with paddings
+ * out[row * ptr_step_out + col * step_out] = in1[row * ptr_step_in1 + col * step1] + in2[row * ptr_step_in2 + col * step2];
+ * The implementation use ANSI C and could be compiled and run on any platform
+ *
+ * @param[in]  input1: input array 1
+ * @param[in]  input2: input array 2
+ * @param[out] output: output array
+ * @param[in]  rows: matrix rows
+ * @param[in]  cols: matrix cols
+ * @param[in]  padd1: input array 1 padding
+ * @param[in]  padd2: input array 2 padding
+ * @param[in]  padd_out: output array padding
+ * @param[in]  step1: step over input array 1 (by default should be 1)
+ * @param[in]  step2: step over input array 2 (by default should be 1)
+ * @param[in]  step_out: step over output array (by default should be 1)
+ *
+ * @return
+ *      - ESP_OK on success
+ *      - One of the error codes from DSP library
