s8 elementwise squared difference of two tensors with support for broadcasting.

Parameters:

  • left_shift – [in] Common left shift applied to both inputs before requantization. Bound: the kernel evaluates (value + offset) << left_shift in int32; with full-range int8 inputs and zero-points the widest operand is 255, so left_shift is at most 23. The scale 1 << left_shift is itself representable up to 30. Not validated by the kernel.

Returns:

ARM_CMSIS_NN_SUCCESS on success, or ARM_CMSIS_NN_ARG_ERROR when a pointer is NULL, a dimension is not positive, the two input shapes are not broadcast-compatible, or the output shape is not their broadcast shape.
