FEE/DAQ WS Mission Statement FEE/DAQ Workshop • Focus is on system aspects of the final system • Interim solutions, like n-XYTER, should only be covered in a 'lessons learned from' context. CBM Collaboration Meeting -- Walter F.J. Müller, GSI
FEE/DAQ WS Agenda FEE/DAQ Workshop • Monday • morning: TOF (PADI/GET4 readout) • afternoon: TRD/MUCH ('Gas'-XYTER readout) • Tuesday • morning: STS ('Si'-XYTER readout) • afternoon: MVD/RICH DAQ/FLES Full program and presentations seehttp://cbm-wiki.gsi.de/cgi-bin/view/DAQ/Workshop-2010-02 CBM Collaboration Meeting -- Walter F.J.

DAQ/FLES WG Data Aggregation on separate chip - Communication hub • Motivation: • Data Aggregation: In most cases 2,4, or 8 CBM-XYTER chips (FEBa2, FEBa4, FEBa8, resp.) can be aggregated to fill a 2.5 Gbps link • Increase the bandwidth available per link • Reduce the number of Optical Links • Schemes: • Embedded (aggregation integrated in CBM-XYTER) • Data aggregation and Traffic Managementwith a separate Communication Controller Asic • Clock Distribution • Slow control traffic • Data Readout traffic Communication ‘hub’ 15th CBM Collaboration Meeting 6 Slide: P.
