Silicon Tracking DAQ

Some preliminary thoughts on how to design and develop the DAQ architecture for the Silicon tracking system at the future Linear electron positron collider, are briefly presented here. The proposed structure includes three DAQ levels. The first level is based on a high level processing mix-mode ASIC sitting on the detector. The second level still on the detector is a DSP like interface that will send the processed data to the general DAQ system. Several novel technological aspects are part of this development. The role of the ongoing test beam activities with detector prototypes as training camp is emphasized.
