The new DAQ system which DD is integrated into CODA


Below is a picture discribing the new DAQ system. Communication with ROC is treated by the EB of CODA. The source file for the EB is eb_pr.c. In fact, this component contains a DD producer. Once an event injects into CODA, the DD producer receives that event and passes it onto the later consumer processes. There will be three consumer processes in this simple DAQ if we finish adding data writer to this DAQ. At present, online event display and hbook analysis consumer process are working on mvdonl.lanl.gov. Working source files are dd_ana.c and dd_hbk.c. dd_ana displays events of 152 word length. dd_hbk is an example, which runs HBOOK in DD.
