System architecture

Processor

At the core of pyneurode is the Processor class. A Processor is a multiprocessing.Process that runs in its own Python process and have a item queue (based on multiprocessing.Queue) for input data. A Processor work on the items on its input queue and generate results to be put on the output queue, which in turn are the corresponding input queues for downstream processors.

Message

Processor communicate to each other via Message. A Message is a Python dataclass that has a 3 fields: type, data and optionally timestamp. The type is a string that indicate what data is stored in a Message. It can be any name, as long as downstream processor recognize it. data can be any anything supported by Python’s multiprocessing.Queue.

GUIProcessor and Visualizer

The GUIProcessor is responsible for creating the graphical interface in pyNeurode. It relies on various Visualizer objects to show different visualization for various message type. We use DearPyGUI as our GUI toolkit as it is GPU accelerated and work across all three major platforms (Windows, MacOS and Linux).
