AVR controller specific implementation of the Sigmoid layer in Q7 data-type. For more information about the Sigmoid layer refer to ailayer_sigmoid.h.

Requires avr/pgmspace.h library

Function Documentation

ailayer_sigmoid_q7_avr_pgm()

ailayer_t* ailayer_sigmoid_q7_avr_pgm	(	ailayer_sigmoid_q7_t *	layer,
		ailayer_t *	input_layer
	)

Initializes and connect a Sigmoid layer with the Q7 AVR PGM implementation.

The quantization parameters of the result tensor of the input layer must be defined constant in program memory (PROGMEM). The layer configuration is the same as with ailayer_sigmoid_q7_default().

The quantization parameters of the result tensor are automatically set to {shift = 8, zero_point = -2^7} because the output values are in the interval (0, 1).

Example: Create the layer structure:

ailayer_sigmoid_q7_t sigmoid_layer;

or

ailayer_sigmoid_q7_t sigmoid_layer = AILAYER_SIGMOID_Q7_M();

Example: Initialize and connect the layer:

x = ailayer_sigmoid_q7_avr_pgm(&sigmoid_layer, x);

Parameters

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

Returns

The (successfully) initialized layer structure.
