Function Documentation

synaptogenesis_dynamics_initialise()

bool synaptogenesis_dynamics_initialise	(	address_t	sdram_sp_address,
		uint32_t *	recording_regions_used
	)

Initialisation of synaptic rewiring (synaptogenesis) parameters (random seed, spread of receptive field etc.)

Parameters

[in]	sdram_sp_address	Address of the start of the SDRAM region which contains synaptic rewiring params.
[in,out]	recording_regions_used	Variable used to track what recording regions have been used

Returns

Whether we were successful.

synaptogenesis_dynamics_rewire()

bool synaptogenesis_dynamics_rewire	(	uint32_t	time,
		spike_t *	spike,
		pop_table_lookup_result_t *	result
	)

Trigger the process of synaptic rewiring.

Usually called on a timer registered in c_main()

Parameters

[in]	time	the current timestep
[out]	spike	variable to hold the spike
[out]	result	The result of the population table lookup

Returns

True if a row is to be transferred, false otherwise

Definition at line 220 of file topographic_map_impl.c.

synaptogenesis_row_restructure()

bool synaptogenesis_row_restructure	(	uint32_t	time,
		synaptic_row_t	row
	)

Perform the actual restructuring of a row.

Parameters

[in]	time	The time of the restructure
[in]	row	The row to restructure

Returns

True if the row was changed and needs to be written back

Definition at line 376 of file topographic_map_impl.c.

synaptogenesis_spike_received()

void synaptogenesis_spike_received	(	uint32_t	time,
		spike_t	spike
	)

Indicates that a spike has been received.

Parameters

[in]	time	The time that the spike was received at
[in]	spike	The received spike

Definition at line 383 of file topographic_map_impl.c.

synaptogenesis_n_updates()

uint32_t synaptogenesis_n_updates

(

void

)

Definition at line 387 of file topographic_map_impl.c.

print_post_to_pre_entry()

void print_post_to_pre_entry

(

void

)

Print a certain data object.
