Function Documentation

arm_cmsis_nn_status arm_vector_sum_s8(int32_t *vector_sum_buf, const int32_t vector_cols, const int32_t vector_rows, const int8_t *vector_data, const int32_t lhs_offset, const int32_t rhs_offset, const int32_t *bias_data)

Calculate the sum of each row in vector_data, multiply by lhs_offset and optionally add s32 bias_data.

Parameters:

  • vector_sum_buf – [inout] Buffer for vector sums

  • vector_cols – [in] Number of vector columns

  • vector_rows – [in] Number of vector rows

  • vector_data – [in] Vector of weigths data

  • lhs_offset – [in] Constant multiplied with each sum

  • rhs_offset – [in] Constant added to each vector element before sum

  • bias_data – [in] Vector of bias data, added to each sum.

Returns:

The function returns ARM_CMSIS_NN_SUCCESS - Successful operation
