Sorting of STS-XYTER2 data for microslice building for CBM experiment

The article describes the architecture of the data sorting and aggregation module for the triggerless high energy physics experiment data acquisition. The described module is able to revert shifts in the input data order, which are introduced by the detector readout modules. The sorted data is aggregated into a single stream and then divided into packages containing samples acquired in consecutive time intervals. The presented article describes the usage of the heap sorting algorithm for restoring the correct data order. Data stream aggregation techniques, used in the presented module, are described. The paper contains a block diagram of the presented module and resource utilization summary generated after implementation.
