The Jefferson Lab Common Online Data Acquisition System (CODA) is in its second generation of release and is currently begin used in all three existing experimental halls. CODA was designed as a modular, extensible software toolkit from which data acquisition systems of varied complexity could be built. However, because of its software oriented design, CODA's performance is largely defined by the hardware and operating systems upon which it runs.
The implementation of the CODA data acquisition system in each experimental hall will be discussed with an emphasis on current system limitations both in hardware and software.
