DAQ Report
Graham gave a brief update on the status of DAQ projects and writing assignements. He will give a full report on the EMU next meeting.
- EMU (Event Management Unit) is basic CODA3 building block that accepts input data, transforms it, then sends the result out.
- Many utilities can be built from EMU: EB, ER, etc.
- EMU framework, XML config, and diagnostic interface completed.
- Code for moving data ready, but needs integration into EMU framework.
- EB part not ready, butsome testing using earlier prototypes successful.
- EMU build thread parallelizable for multi-core environment.
- DAQ group has organized writing assignments for subsystem review docs.
- Doc for each component plus top-level doc planned.
- Dave D asked if a "hardware switch architecture" is preferable to a "divide-and-conquer" strategy, i.e. do all rocs talk to all EB's, or are the rocs divided up among the EB's. DAQ group consensus was to divide-and-conquer at the roc level, although the other strategy could work.
250 MHz L1 Trigger Test and 200 kHz Front End Triggering Test
- TI may not be ready by review, so no 200 kHz crate triggering test, but can present design and architecture.
- Libs for board readout done, so some tests can be performed.
- No new 250 MHz testing planned, what we have now is what will be presented. More tests by end of this fiscal year.
- Plans for additional prototyping and testing by Sep, but not for May review.
May Subsystem Review
Elke gave an overview of what to expect at the review, and showed a preliminary agenda.
- Final pre-brief material will be placed on Elke's official subsystem review page.
- Preliminary pre-brief and other material will be place in May 2008 Subsystem Review
