however the Propeller 1 has a 16-bits addressing space, it's a MPU,

OTOH, now the YASEP has a serious competitor...
http://www.lowrisc.org/ looks kind of interesting if I can't talk Yan
into a yasep64.
You can't "talk me into" it because it's pointless, the YASEP is a MPU
and will remain so. It's good for MPU stuff and not great for
application processing.
For that last domain, you forget too easily that I have designed FC0,
it's well tucked up my sleeve
but it is not abandonned :

You get a compiler-friendly ISA, a pipeline-friendly memory system,
64-128-256-512bits SIMD...
And yes it has not been touched in 10 years :-P
I have not looked far enough into lowRISC to see if it's actually
endian-sane.
I'll have to look closely at the ISA, I wonder how much or RISC-V was
copied from MIPS...
Anyway, the tide of Open/Free Hardware is slowly rising :-)
