Detailed Description

RDH v2 this is the version 2 definition which probably has not been adapted by any FEE https://docs.google.com/document/d/1FLcBrPaF3Bg1Pnm17nwaxNlenKtEk3ocizEAiGP58J8

  |---------------|---------------|---------------|---------------|

0 | zero | size |link id| FEE id | block length | vers |

1 | heartbeat orbit | trigger orbit |

2 | zero |heartbeatBC| trigger type | trigger BC|

3 | zero | par | detector field| stop | page count |

Field description:

  • version: the header version number
  • block length: assumed to be in byte, but discussion not yet finalized
  • FEE ID: unique id of the Frontend equipment
  • Link ID: id of the link within CRU
  • header size: number of 64 bit words
  • heartbeat and trigger orbit/BC: LHC clock parameters, still under discussion whether separate fields for HB and trigger information needed
  • trigger type: bit fiels for the trigger type yet to be decided
  • page count: incremented if data is bigger than the page size, pages are incremented starting from 0
  • stop: bit 0 of the stop field is set if this is the last page
  • detector field and par are detector specific fields
