LibrariesLocal level processing

Two class approachThe mother class usually binds with the ADF:I/O methods, configuration, initialization

The daughter class usually overloads the processing method where the

job is done

ORGANIZATION IN&OUT NARVALAll the C/C++ code is in a dedicated machine where all the librarieshave been ported and build. Afterwards they are copied to a commonnfs directory, loaded and configured inside NARVAL.

Self contained emulator and shared library emulator(for debugging

purpose).

Global Level

Event Builder :builds the event (TS or EN), moves from the same key(data:psa) of different crystals in event:data:psa

Merger :assembles two different keys (ranc1,event:data:psa) inevent:data

Tracking :deconding,coding, OFT, Doppler corr

Consumer :dumps ADF data on disk

Summary and conclusions

ON-LINE analisys at a rate of & 5 kHz/crys, with two ATCs

AGAVA coupling and sync achieved

System looks easily scalable and reliable

Major limit: debug
