@brief Initialization function for the floating-point FIR decimator. @param[in,out] S points to an instance of the floating-point FIR decimator structure @param[in] numTaps number of coefficients in the filter @param[in] M decimation factor @param[in] pCoeffs points to the filter coefficients @param[in] pState points to the state buffer @param[in] blockSize number of input samples to process per call @return execution status

  • \ref ARM_MATH_SUCCESS : Operation successful
  • \ref ARM_MATH_LENGTH_ERROR : blockSize is not a multiple of M
