FED Firmware

• FED Firmware Developments
• SPY channel. Synchronised to Frames. Needs
  testing at CERN.
• Fine Timing Skew calibration improved. Needs
  verifying in CERN system. Important.
• TTC Channel B e.g. APVe broadcast. Tested at
  RAL. Testing at CERN in progress.
• Various improvements to monitoring, new status
  words
• Improvements to Throttle and overflow handling
• Event Downscaling for Fast Raw pedestal readout
  tests to investigate noise at detector edges.
  Implemented, under test.
• Event Format changes for optimal Filter software
  efficiency tbd.
• VME 64 Block Transfers tbd
• Outstanding problems
• Missing buffers reported in TIF tests. Have
  recent firmware releases fixed this?
• ZS Lite initialisation problem.
• Intermittent Compact Flash new firmware file
  reloading failures
• Changes needed based on operation experience,
  resets etc
