core library

The core library provides support for backends. The core library provides the classes required for interacting with backends and performing application tasks.

The table below contains descriptions of the library components.

The core library components

Component	Description
Backend	Base class for specific backend implementations.
BaseData	Structure defining a set of base data.
continuously_uid_generator	Class implementing a generator of unique IDs.
Device	Base class of devices.
MessageBus	Class implementing an interface for the message bus.
MessageEndpoint	Class implementing an interface for the message bus endpoint.
Population	Template class that implements the container of neurons of the same model. A neural network node with a set of attributes. Based on the neuron attributes and the sequence of input signals, a certain mathematical function is calculated. The result of the function is a synaptic impact or its absence.
Projection	Template class that implements the container of synapses of the same type. Neuron junction with the main function to transmit a signal from one neuron to another. Each neuron can be connected to multiple synapses.
Subscription	Class implementing the message subscription.
TagMap	Class implementing an interface for the tag dictionary.
UID	Class defining unique identifiers.
uid_hash	Function implementing hashing of UIDs.
messaging	Namespace that contains message interfaces.
tags	A namespace that contains the names and value types of known tags.

The figure below shows how the library components interact.

In the Kaspersky Neuromorphic Platform, the BaseData structure contains basic information about an object and includes UID and TagMap. The BaseData structure is used in the following classes: Projection, Population, and Backend. Therefore, each of them has a UID and a set of tags with the TagMap values.

The Population and Projection classes receive and send messages that are implemented in the classes of the messaging namespace. Messages contain the sender's UID in the header.

The Backend class contains the Device and MessageBus classes. The MessageBus creates MessageEndpoint and interacts with them by exchanging messages. Each MessageEndpoint has a container of the Subscription class.
