Summary: multiple register sets ?


So has anyone done research to see if it might be worthwhile to
implement a machine with multiple sets of registers (say 16 sets
of 64 registers, with register windows)?  This would cut down on
the overhead of conext switching a lot assuming that not too many
processes were "active" at once.  It would probably add a lot to
the complexity of the system though...
