After informing a task about the arrival of data, GSEOS accesses the whole data block or single data items which are defined in the block definition. The Decoder module also allows you to create new data blocks. At any given time the system uses one of the mutually exclusive data sources available: BIOS, Recorder, Net, or a custom data source. I.e. when data is played back from disk the Recorder is the data source and all data coming in from other data sources is discarded.
Data processing within GSEOS is inherently data driven. A configuable queue acts as a buffer between data sources and consumers.
