This is one of those cases where links would help:

https://web.archive.org/web/20160428161757/http://research.microsoft.com:80/en-us/projects/e2

(deleted page from Microsoft Research’s website)

Referring article here:

https://fossbytes.com/microsoft-linux-windows-10-e2-edge-cpu/

  Microsoft has called E2 “a research project, and there are currently
  no plans to productize it.”

Not sure this will help.  I tihnk Z/Architecture has a few instructions
along these lines.  I don't believe they are actually in use
anywhere.

This sounds like The Return of the Son of VLIW.

  Thanks, can't recall the original sighting but have since been through
both of those pages.

Must we fear the day when Microsoft comes to own the web archive?

AIUI, the essence of E2/EDGE is that the scheduling is done
intelligently by the computer, whereas with VLIW it is done
by the compiler, the latter being unable to deal with performance
issues caused by programs dynamic behaviours and loadings.

With a touch of a 'data-flow' architectural bent.

At a much much slower speed, the joy of playing
with LabView!

The identification of blocks that can be executed independently is
 done by hardware? Wow!

Bottom line: having a clue what the hardware actually does will
 always be useful for understanding why things fail.
