Aloha,
I'm looking for your recommendations on the latest data acquisition
hardware, compatible with EPICS.
Our Secondary Mirror system at Gemini has a 1 meter diameter,
55 kg mass. There's 3 degrees of freedom and a 5 kHz control loop.
The system was designed in the 90's by Lockheed Martin, based on
a DOS PC with an ISA backplane (PICMG 1.0) and a DSP data
acquisition board with 16 bit ADC's and DAC's. The DOS PC interfaces
with an EPICS IOC via Reflected Memory.
In 2010 I did a conceptual redesign based on a Hytec Blade 9010 using
IP cards and an Intel CPU running RTEMS. Today it seems FPGA's are
a popular choice for data acquisition. Perhaps a Xylinx zynq solution?
Would anyone still consider VME?
I have no requirement for 5 kHz EPICS control. Although that's intriguing.
Thanks for your time.
