I really don't know a whole heck of a lot about where mips is going.
Certainly they remain strong in the embedded market (I do like the
edgerouter X a lot), but as for their current direction or future
product lines, not a clue.
I used to know someone over there, maybe he's restored new directions.
Last I recall he was busy obsoleting a whole lot of instruction space
in order to make room for "new stuff". He'd even asked me if adding an
invsqrt to the instruction set would help, and I sadly replied that
that bit of codel was totally invisible on a trace.....
I really like(d) mips. ton of registers, better instruction set than
arm (IMHO), no foolish processor extensions.
