What i found intriguing is that Xilinx Q-Pro family is supposedly ITAR-controlled, so how are Chinese running those on the far side of the moon is .. an interesting question. Further, googling "XQR2V3000" "AT697F" and together returns some interesting results from UK based research .. Also, Chang'e actually does impressive amounts of processing on board, as they employ vision-based autonomous guidance algorithms for landing. Thats unprecedented

That's really interesting, it hadn't occurred to me that an FPGA would ever fall under ITAR, then again, after quickly scanning Wikipedia, I didn't even realize things like night vision fall under that too, but I guess it makes sense.

  Yeah, a lot of devices that are powerful enough (subject to fudging) that are uncommitted but can be committed to Bad Stuff seems to be ITAR regulated. Another thing that might be the trigger is processors with real time capabilities. I was surprised to see that the Beaglebone (with its very powerful PRU) was ITAR regulated, but the Raspberry Pi (not a lot of real time stuff) wasn't.

    AM335x PRUs are exactly the reason why its under ITAR. Hard-realtime running alongside general-purpose OS

Unprecedented, except for this paper[1] from 2010 and the NASA CoNNeCT project[2]. Both of which use the same hardware. But it is unprecedented in that nobody has landed on the far side of the moon before.

  Unprecedented in that it has never been used in space before. Studies and projects yes. NASA is working on their own version for Mars 2020 rover, although the system ( called ALHAT ) hasn't been officially included yet
