New Crate Controller DevelopmentNew Crate Controller DevelopmentNew Crate Controller DevelopmentNew Crate Controller Development

A VMEbus Controller with Gigabit Ethernet – A custom board designed and

developed at OSU– Based on XILINX Virtex-II Pro– Custom firmware.– Optical transceiver (for Gbit Ethernet) – Communicates with stand-alone PC

(in USC55) via Gigabit Ethernet

It’s Alive !

Measured: Continuous Read/WriteVME Transfers at 120 Mbit/s

DDU PrototypeDDU PrototypeDDU PrototypeDDU Prototype• Functions

– Merge data from 13 DMBs– Perform error checking

and status monitoring (CRC, word count,

L1 number, BXN, overflow, link status)

– Communicates w/FMM

• Large Buffer Capacity– 2.5 MB buffer – Average DDU data volume

estimated to be 0.4kB per L1A at LHC (@1034 lumi)

– Buffer can hold over 6000 events

• TTC signals from DCC • Slow control via VME

• Data Concentration– Merge data from 9 DDUs– send merged data to

central DAQ via 1 or 2 SLINKs

– Has two optional GbE spy data path

• Fast Control– Receive TTC fiber

signals using TTCrx, – Fanout L1A, LHC_clock

and other TTC signals to DDUs
