Function Documentation

synapse_structure_get_update_state()

static update_state_t synapse_structure_get_update_state ( plastic_synapse_t  synaptic_word, index_t  synapse_type  )

inlinestatic

Get the update state from the synapse structure.

Parameters

[in]	synaptic_word	The plastic synapse data
[in]	synapse_type	What (supported) type of synapse is this?

Returns

The update state

Creates the update state, using weight-dependence to initialise the weight state, and copying other parameters from the synaptic word into 32-bit form.
