s8 Vector by Matrix (transposed) multiplication using per channel quantization for output

Parameters:

  • lhs – [in] Input left-hand side vector

  • rhs – [in] Input right-hand side matrix (transposed)

  • kernel_sum – [in] Kernel sums of the kernels (rhs). See arm_vector_sum_s8 for more info.

  • bias – [in] Input bias

  • dst – [out] Output vector

  • lhs_offset – [in] Offset to be added to the input values of the left-hand side vector. Range: -127 to 128

  • dst_offset – [in] Offset to be added to the output values. Range: -127 to 128

  • dst_multiplier – [in] Output multipliers

  • dst_shift – [in] Output shifts

  • rhs_cols – [in] Number of columns in the right-hand side input matrix

  • rhs_rows – [in] Number of rows in the right-hand side input matrix

  • activation_min – [in] Minimum value to clamp the output to. Range: int8

  • activation_max – [in] Maximum value to clamp the output to. Range: int8

  • address_offset – [in] Memory position offset for dst. First output is stored at ‘dst’, the second at ‘dst + address_offset’ and so on. Default value is typically 1.

  • rhs_offset – [in] Offset to be added to the input values of the right-hand side vector. Range: -127 to 128

Returns:

The function returns ARM_CMSIS_NN_SUCCESS
