Function Documentation

connection_generator_kernel_initialise()

static void * connection_generator_kernel_initialise ( void **  region )

static

Initialise the convolution-kernel connection generator.

Parameters

[in,out]

region

Region to read parameters from. Should be updated to position just after parameters after calling.

Returns

A data item to be passed in to other functions later on

connection_generator_kernel_free()

static void connection_generator_kernel_free ( void *  generator )

static

Free the convolution-kernel connection generator.

Parameters

[in]

generator

The generator to free

connection_generator_kernel_generate()

static bool connection_generator_kernel_generate ( void *  generator, uint32_t  pre_lo, uint32_t  pre_hi, uint32_t  post_lo, uint32_t  post_hi, uint32_t  post_index, uint32_t  post_slice_start, uint32_t  post_slice_count, unsigned long accum  weight_scale, accum  timestep_per_delay, param_generator_t  weight_generator, param_generator_t  delay_generator, matrix_generator_t  matrix_generator  )

static

Generate connections with the convolution-kernel connection generator.

Parameters

[in]	generator	The generator to use to generate connections
[in]	pre_slice_start	The start of the slice of the pre-population being generated
[in]	pre_slice_count	The number of neurons in the slice of the pre-population being generated
[in]	pre_neuron_index	The index of the neuron in the pre-population being generated
[in]	post_slice_start	The start of the slice of the post-population being generated
[in]	post_slice_count	The number of neurons in the slice of the post-population being generated
[in]	max_row_length	The maximum number of connections to generate
[in,out]	indices	An array into which the core-relative post-indices should be placed. This will be initialised to be max_row_length in size

Returns

The number of connections generated
