That said, the original application of this chip is realtime sensor data timestamped with nanosecond precision. A nommu system can actually be a benefit here because even soft page faults trigger enough latency to screw up that kind of precision. So you'll still be able to configure the bitstream to build without one even after it's added.
(Of course keeping a nanosecond-precise clock in small distributed devices is its own very hard problem... and that peripheral the company is _not_ open sourcing. :)

That’s *your* original application. Other people may wish to do more fun things with it.
You had a huge chance – your slides started with the idea of *fully* opening a contemporary unixoid system. Using this as replacement for ARM (which are “dead on hitting market”, incompatible with itself, money-driven, inconsistent, not compatible in any direction, and adding stuff like trust zones, EFI and Restricted Boot, and which I never liked) and MIPS (which I liked only a bit more) could be genius. (Though I admit at being an i8088 guy first and foremost.)
