Function Documentation

ailayer_relu_calc_result_tensor_params_q31_default()

void ailayer_relu_calc_result_tensor_params_q31_default

(

ailayer_t *

self

)

Calculate and set the quantization parameters for the result tensor of the ReLU Q31 default implementation.

Implementation of ailayer.calc_result_tensor_params.

The quantization parameters are pre-defined and the same as in the corresponding math function aimath_q31_default_relu().

Parameters

*self

The layer structure

ailayer_relu_calc_result_tensor_params_q7_default()

void ailayer_relu_calc_result_tensor_params_q7_default

(

ailayer_t *

self

)

Calculate and set the quantization parameters for the result tensor of the ReLU Q7 default implementation.

Implementation of ailayer.calc_result_tensor_params.

The quantization parameters are pre-defined and the same as in the corresponding math function aimath_q7_default_relu().

Parameters

*self

The layer structure

ailayer_relu_f32_default()

ailayer_t* ailayer_relu_f32_default	(	ailayer_relu_f32_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a ReLU layer with the F32 default implementation.

Example: Create the layer structure:

ailayer_relu_f32_t relu_layer;

or

ailayer_relu_f32_t relu_layer = AILAYER_RELU_F32_A();

Example: Initialize and connect the layer:

x = ailayer_relu_f32_default(&relu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.

ailayer_relu_q31_default()

ailayer_t* ailayer_relu_q31_default	(	ailayer_relu_q31_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a ReLU layer with the Q31 default implementation.

The quantization parameters of the result tensor are automatically set to {shift = input_layer.result.shift, zero_point = input_layer.result.zero_point} because the output values are in the interval [0, max(input_layer.result)].

Example: Create the layer structure:

ailayer_relu_q31_t relu_layer;

or

ailayer_relu_q31_t relu_layer = AILAYER_RELU_Q31_M();

Example: Initialize and connect the layer:

x = ailayer_relu_q31_default(&relu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.

ailayer_relu_q7_default()

ailayer_t* ailayer_relu_q7_default	(	ailayer_relu_q7_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a ReLU layer with the Q7 default implementation.

The quantization parameters of the result tensor are automatically set to {shift = input_layer.result.shift, zero_point = input_layer.result.zero_point} because the output values are in the interval [0, max(input_layer.result)].

Example: Create the layer structure:

ailayer_relu_q7_t relu_layer;

or

ailayer_relu_q7_t relu_layer = AILAYER_RELU_Q7_M();

Example: Initialize and connect the layer:

x = ailayer_relu_q7_default(&relu_layer, x);

Parameters

*layer	The layer structure to initialize.
*input_layer	The prior layer.

Returns

The (successfully) initialized layer structure.
