DAQ Software Architecture Design
• Based on the framework of ATLAS TDAQ and BESIII DAQ,– Online software (almost
reuse ATLAS)• Configure, control, and
monitor the DAQ system • Provide services to data
flow
– Data flow software (ATLAS+BES+DYB)
• Responsible for all the processing and transportation of physics data
