weight_initialise()

address_t weight_initialise	(	address_t	address,
		uint32_t	n_synapse_types,
		uint32_t *	ring_buffer_to_input_buffer_left_shifts
	)

Initialises the weight aspect of an STDP rule.

Parameters

[in]	address	the absolute address in SRAM where the weight parameters are stored.
[in]	n_synapse_types	The number of synapse types
[in]	ring_buffer_to_input_buffer_left_shifts	how much a value needs to be shifted in the left direction to support comprises with fixed point arithmetic

Returns

the end of the weight region as an absolute SDRAM memory address.
