I'm looking at producing an industrial monitoring system as a
replacement for an existing design using the TS-72XX and a TS-7KV. The
TS-7KV has an analogue input option, 8MB of RAM, a fairly large FPGA
and a number of uncommitted 3.3V I/O connected to the FPGA.
It would be a 'relatively' easy task to generate an FPGA which would
read the ADC at a fixed rate into part of the 8MB SDRAM and also take
data out of another section of the SDRAM and send it to a DAC
connected to a few of the uncommited logic I/O.
You could then simply store the output waveform data to the SDRAM FIFO
on the TS-7KV and forget about it, and pull the input stream from the
SDRAM input FIFO as fast as it's available...
