4 Apr 2010SCT DAQ - HSIO Firmware Update Firmware Update Development is active, many improvements –Coupled closely to software development Multi-stream readoutMulti-stream readout –Handles 16 streams of ABCN data (i.e. 8x BCC) –Proper flow control –Scalable DAQ ConnectivityDAQ Connectivity –Fibre Ethernet –Copper Ethernet (up to 100Mb, likely 1Gb with new HSIO) –USB soon DAQ controlDAQ control –Writable registers – controls modes/readout clocks etc.

5 Apr 2010SCT DAQ - HSIO Firmware Update In progress USB Firmware is written, but untested on HSIOUSB Firmware is written, but untested on HSIO Full blown histogrammer systemFull blown histogrammer system –LBNL Module has been integrated, but untested Works on HSIO for ABCD, but not with SCTDAQ firmwareWorks on HSIO for ABCD, but not with SCTDAQ firmware Improved packet handlingImproved packet handling –Simulate more realistic “asynchronous” conditions –Add multiple packets for long events capability I2C MonitoringI2C Monitoring –Started at LNBL –Needs dedicated data-streams on HSIO and control logic User selectable header/trailer, raw stream captureUser selectable header/trailer, raw stream capture –For BCC ID/register readback - has no header Jumper selectable DAQ interface – Fibre/Copper/USBJumper selectable DAQ interface – Fibre/Copper/USB

6 Apr 2010SCT DAQ - HSIO Firmware Update Next steps Individual delays on all input streamsIndividual delays on all input streams Register readbackRegister readback –Currently we can only look at the display! Add more status registersAdd more status registers –Trigger/header counters Implement other types of control and readbackImplement other types of control and readback –Blocks –FIFOs –Autonomous status reports Full Histogrammer sub-systemFull Histogrammer sub-system –Assess best structure – 1 per channel or shared? Scale to 48 channelsScale to 48 channels –May need effort on logic reduction to fit FPGA –Coupled to histogrammer config

10 Apr 2010SCT DAQ - HSIO Firmware Update SCTDAQ Stavelet GUI Features: Menu bar Dialog boxes to set parameters Tabbed display shows data for 4 modules

11 Apr 2010SCT DAQ - HSIO Firmware Update But does it work? This preliminary plot shows a raw data burst for one ABCN-25/BCC module. We have recorded analogue test data from a single hybrid, but not yet from a module. To be continued…
