This page describes some ideas for hardware-support which could allow for DQM on every event, not just a small subset. Simple things like checking for errors in the data format would be easy, but anything which involves (i.e.) calibration would be more complicated.

Anyway, here are some basic ideas:

• Parse the data in hardware such that the following can be efficiently accessed
  • DCC header and trailer
  • HTR headers
  • Trigger primitives (by channel)
  • QIE data (by channel)

Provide the capability to make 1D and 2D histograms with fixed bin sizes. Note that a particular data item might result in filling more than one histogram, so some parallelism is required.

The hardware should be able to handle a full data rate of something like 800Mbytes/sec to allow for DAQ upgrades.
