  1. CMIB development Bruce Rowen, NRAO

  2. Some numbers • Still using 2.6.13 kernel • Possible squeeze on station board CMIB resources • Current CMIB is EOL, replacement is about 4x “better” • 256MB memory now about $30US • 125k lines of c code

  3. Drivers • FPGA programming • Installed on both prototypes, loads based on simple script, automatic on boot. • Sysmon system monitoring • Collects A/D conversion data and formats into temps/voltages based on simple configuration script. • Added correlator voltage monitoring • Need to integrate with a “data task” to bundle and sample for monitoring. • Add correlator powerup control and FPGA power control modes. • MCB • Provide direct-wired access to hardware • IPC (Inter-process communication) • Provides basic data exchange ‘pipes’ and virtual device access for ancillary data (i.e. CRC collection, model exchange, etc.) • Added to allow for more device minor numbers and individual Filter device minors for delays and LUTs. New!

  4. Baseline Board MAHsToDos • Recirculator • Need features for HM receivers • Correlator • LTA • Need to test accumulator R/W (needed?) • Need to provide for sequenced correlator chip powerup (sysmon ?) • Ethernet • Frame capture (first dump) needs fixing • Fanout/config • Needs MAH • Supervisor • Finish MAH, add features.

  5. Station Board MAHsToDos • Input – add clock edge selection • Delay – test buffer R/W, adapt for DMA • WBC – • Output – radar data capture UI • Timing – HES generation • VSI – test • Supervisor – add system monitoring, task watchcdog control

  6. Station Board Data Tasks • Wideband state count monitoring • Widband Auto Correlation • Up to 32 product sets • CRC monitoring • Power metering • RFI metering • Filter clip metering • Filter tone extraction • Need to manage models • Requantizer monitoring • Time interval count monitoring • Need to finish up.
