[erlang-questions] 16-bit Erlang: crazy? Or just stupid?

[Jesper Louis Andersen]

In principle, with enough work, this is possible, though in a modern world
I think the 16 bit address space ends up being too small. The 32 bit
address space is quite viable however, and that experiment has been done,
see the halfword-emulator for Erlang.

The idea is to run Processes in a 32bit space, but keep ETS tables and
other things in a 64 bit space. The end result is less memory pressure for
processes, smaller pointers in many cases and so on.

I'm somewhat hesitant to say we would win much by having smaller data paths
down to 16 bit. It doesn't look like this is the primary limitation of
modern CPU architectures: power, memory bandwidth, and a tiny issue width
is.
