Functions

SYMBOL_VISIBLE void send_vectors (stadls::vx::v3::PlaybackProgramBuilder &builder, const pybind11::array_t< uint_fast16_t > &vector, const size_t num_sends, const size_t wait_period, const halco::hicann_dls::vx::v3::SynramOnDLS synram_coord, const size_t synram_selection_bit)

Generate events for the given vector in hagen mode.

Parameters

  • builder – Builder to append writes to

  • vector – Array containing the input vector

  • num_sends – Number of repeats of the whole vector

  • wait_period – Wait time between two successive events

  • synram_coord – Coordinate of synapse array to target with the events

  • synram_selection_bit – Determines which bit in the event label selects the synram

namespace ccalix::hagen::multiplication::detail

Functions

haldls::vx::v3::SpikePack1ToChip prepare_event(const haldls::vx::v3::SynapseQuad::Label address, const halco::hicann_dls::vx::v3::SynapseDriverOnSynapseDriverBlock target_driver, const halco::hicann_dls::vx::v3::SynramOnDLS synram_coord, const size_t synram_selection_bit)

Return a spike pack to chip, containing an event reaching the desired synapse driver on the desired synram.

Parameters

  • address – Address that is sent to the driver. The MSB reaches the synapses, the lower 5 bit encode the desired activation.

  • target_driver – Coordinate of target synapse driver.

  • synram_coord – Coordinate of target synapse array.

  • synram_selection_bit – Bit position that selects synapse array.

Returns

Spike packet to chip.

void write_capmem_row(builder_t &builder, const halco::hicann_dls::vx::v3::CapMemRowOnCapMemBlock row, const pybind11::array_t<uint_fast16_t> &values)

Attach write commands for a single, full row of non-global capmem cells to a given builder.

Template Parameters

builder_t – Type of the builder in use

Parameters

  • builder – Builder writes are appended to

  • row – Capmem row to be written

  • values – Array of payload data to be written to the given capmem row

namespace spiking
namespace ccalix::spiking::correlation_measurement

Functions

SYMBOL_VISIBLE pybind11::array_t< uint_fast16_t > evaluate_correlation (std::vector< stadls::vx::v3::ContainerTicket > tickets)

Evaluate correlation reads in given list of tickets.

Parameters

List – of read tickets, as returned by the read_correlation() function.

Returns

Numpy array containing all reads. It will be shaped (4, 256, 2) for the entries in a quad, the rows, and the causal/acausal correlation.

SYMBOL_VISIBLE std::vector< stadls::vx::v3::ContainerTicket > read_correlation (stadls::vx::v3::PlaybackProgramBuilder &builder, const halco::hicann_dls::vx::v3::SynapseQuadColumnOnDLS quad, const halco::hicann_dls::vx::v3::SynramOnDLS synram)

Read CADCs in given quad column.

Returns a list of tickets for each row.

Parameters

  • builder – Builder to append reads to.

  • quad – Quad coordinate to be read.

  • synram – Synram to be used.

Returns

List of read tickets, ordered [causal row 0, acausal row 0, causal row 1, …]

SYMBOL_VISIBLE void reset_correlation (stadls::vx::v3::PlaybackProgramBuilder &builder, const halco::hicann_dls::vx::v3::SynapseQuadColumnOnDLS quad, const halco::hicann_dls::vx::v3::SynramOnDLS synram)

Reset all synapse correlations in given quad.

Parameters

  • builder – Builder to append instructions to.

  • quad – Quad column to be reset.

  • synram – Target synram coordinate.

SYMBOL_VISIBLE void send_postpulse (stadls::vx::v3::PlaybackProgramBuilder &builder, const halco::hicann_dls::vx::v3::SynapseQuadColumnOnDLS quad, const halco::hicann_dls::vx::v3::SynramOnDLS synram)

Reset the given quad of neurons, sending an STDP postpulse to synapses.

Parameters

  • builder – Builder to append instructions to.

  • quad – Quad column to reset neurons in.

  • synram – Target synram coordinate.

SYMBOL_VISIBLE void send_prepulse (stadls::vx::v3::PlaybackProgramBuilder &builder, const halco::hicann_dls::vx::v3::SynramOnDLS synram, const haldls::vx::v3::SynapseQuad::Label address)

Send a PADI event to all drivers, i.e.

an STDP prepulse to all synapses.

Parameters

  • builder – Builder to append instructions to.

  • synram – Synram coordinate of synapses to stimulate.

  • address – Address to be sent to synapses.
