FEC/SIU controller – current RCU setup • Based on the PLDA commercial PCI-board • One PLDA-RCU reads out channel by channel up to 13 FECs • Data is stored in internal memory and transferred via PCI to the PC memory. This is done on a channel by channel basis. • Linux application (mini-DAQ, API, device driver) merges the data from each channel into one subevent.
RCU-FEE integration: ReadOut of ALTROs/FECs via PCI using PLDA prototype done (channel by channel) Configuration of ALTROs via PCI using the FE-Bus/ALTRO protocol done RCU-DDL integration: Transfer of data from PLDA-RCU ext. Memory to DDL (current SIU mezzanine) done Writing of status reg. on PLDA-RCU from DDL(SIU mezzanine) done Writing blocks of data from DDL (SIU mezzanine) to PLDA-RCU memory (int. and ext.) done Firmware status
Migration to prototype II – next steps • Transfer of current design to Prototype II (done). • Testing of data transfer from Prototype II external memory to new SIU card. • Building larger fragments (up to full subevent) in RCU external memory (consisting of data from all active channels on all ALTROs/FECs connected to the RCU front end branches) – optimize performance/latency vs memory usage. • Improve PCI readout speed by DMA engine • Merging the Front End and DDL/SIU designs to send data via the new SIU to the RORC/DAQ.
DCS • Backend interface to DCS • OPC server • Fieldbus • Profibus • Ethernet • Frontend interface • Profibus slave ASIC + SM • Ethernet chip + NIOS core
