edit:
Hi10P won't work on ARM or even Intel ATOM processors (maybe one day, but none of the current ones in 2012 would do it). Hi10P can't be hardware decoded (which is to say, no one makes hardware decoders for them and no company plans to add Hi10P hardware decoding in the foreseeable future), which is what Raspberry-Pi, Android, ATOM processors, and some AMD APU systems require for playback smooth demanding video (Hi10P is very demanding). Thus, Hi10P requires CPU/software decoding.
A safe bet would be at least a core2duo processor (or equivalent AMD) or higher.
