.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	undef

used for unspecified quantization kind

.. index:: pair: enumvalue; static_sazp
.. _doxid-group__dnnl__api__attributes_1gga43df4b809a4544d34bbc106d3e409b2ca000df1fbb9ecf80708c726fb84d674c3:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	static_sazp

static quantization mode: quantization parameter is computed ahead of time and passed to oneDNN as an input.

.. index:: pair: enumvalue; dynamic_mx
.. _doxid-group__dnnl__api__attributes_1gga43df4b809a4544d34bbc106d3e409b2ca10dabb84b08ade6e41ee83eba1e96f9d:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dynamic_mx

dynamic quantization mode following OCP MX spec: quantization parameter is computed by oneDNN following the OCP MX spec formula and written as an output.

.. index:: pair: enumvalue; dynamic_fp
.. _doxid-group__dnnl__api__attributes_1gga43df4b809a4544d34bbc106d3e409b2caf962028f6156d4785b104f7f0f362685:

.. ref-code-block:: cpp
	:class: doxyrest-title-code-block

	dynamic_fp

dynamic quantization mode where quantization parameter is computed by oneDNN as :math:`scale\_dt(amax(X) / max(dst\_dt))` in ``f32`` then converted to a scale type and written as an output.
