Upgrade of Readout firmware

Proposal

Data Format

  • Data are now output per TDC channel
  • The Trigger TDC is allways channel 0
  • The mapping between TDC and PETIROC is direct:
    • Channel 1 of TDC $ \rightarrow $ $\alpha$ Channel 0 of PETIROC
    • ..
    • Channel 24 of TDC $ \rightarrow $ Channel 23 of PETIROC
    • It allows to extend easily the number of channels and will only force to resolder adapter boards

The output of a FEB now consists of:

  • A Header packet :
Tag Absolute BXID GTC 64 or 128 channels lengths
2 bytes 6 bytes Readout time in 25 ns (81 j) 4 bytes 64 or 128 bytes , # channels per TDC
