CBM Online Meeting

• V. Friese: Having data from each STS sensor / module inside a single component / FLIM link would be very advantageous from the software point of view (see presentation). This is currenty not used in the implementation of the online binary, but will be soon.
• J. Lehnert: From the cabling perspective, such a solution is possible. See presentation in the DAQ meeting of 5 November 2025.
• D. Hutter: This is the solution currently followed by the DAQ group. It is not clear yet, however, that the FPGA resources are sufficient to realize such a connection scheme. As a fallback, a solution where two FLIM links represent the complete data of a set of modules is possible. Softwarewise, this would add complexity which we would like to avoid, but it is still better than the current implementation of combining data of all components after unpacking to a single array and then sorting these w.r.t modules in a separate step.

The necessary tools to benchmark the current online binary are available and can be used for optimisation: XPU timer (F. Weiglhofer) and the usual profiling tools.
