Detailed Description

Recently spiked partners selection rule.

Definition in file last_neuron_selection_impl.h.

Function Documentation

partner_spike_received()

static void partner_spike_received ( uint32_t  time, spike_t  spike  )

inlinestatic

Notifies the rule that a spike has been received.

Parameters

[in]	time	The time that the spike was received at
[in]	spike	The spike that was received (includes the sending neuron ID)

Definition at line 36 of file last_neuron_selection_impl.h.

potential_presynaptic_partner()

static bool potential_presynaptic_partner ( uint32_t  time, uint32_t *restrict  population_id, uint32_t *restrict  sub_population_id, uint32_t *restrict  neuron_id, spike_t *restrict  spike, uint32_t *restrict  m_pop_index  )

inlinestatic

Choose the potential (remote) synaptic partner.

Randomly (with uniform probability) select one of the last received spikes, and uses the source neuron from that.

Parameters

[in]	time	The current time
[out]	population_id	The ID of the other population
[out]	sub_population_id	The ID of the subpopulation (corresponds to remote SpiNNaker core handling the population)
[out]	neuron_id	The ID of the neuron within the subpopulation
[out]	spike	The spike that made this a meaningful choice
[out]	m_pop_index	The master population table index

Returns

True if a choice was made
