arm_cmsis_nn_status arm_lstm_unidirectional_f32(const float32_t *input, float32_t *output, const cmsis_nn_lstm_params_f32 *params, cmsis_nn_lstm_context_f32 *buffers)

Unidirectional LSTM inference.

Parameters:

• input – [in] Pointer to the input sequence tensor.

• output – [out] Pointer to the output sequence tensor.

• params – [in] LSTM parameters and weights.

• buffers – [inout] Mutable LSTM scratch and state buffers. temp1 and temp2 are sized by arm_lstm_unidirectional_f32_temp1_get_buffer_size() / arm_lstm_unidirectional_f32_temp2_get_buffer_size(), which report 0: the float implementation never dereferences them and both may be NULL.

Returns:

ARM_CMSIS_NN_SUCCESS on success or ARM_CMSIS_NN_ARG_ERROR on invalid arguments.
