Subject: Recommendations for EPICS Based Data Acquisition System

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.

-Matt
