* 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 output: output array
* @param len: amount of operations for arrays
* @param step1: step over input array 1 (by default should be 1)
* @param step2: step over input array 2 (by default should be 1)
* @param step_out: step over output array (by default should be 1)
*
* @return
* - ESP_OK on success
* - One of the error codes from DSP library
