I think it is one that is constructed with programmable logic using the
normal programmable logic tools.  This is in contrast to a hard-core
processor, which is laid out in a more custom manner.  Hard core
processors can be present on an IC with programmable logic, but it is
inserted as a single large piece of logic, rather than build with the
standard programmable parts.

Soft core is more flexible, but hard core has better performance: size,
speed, low power.

I suppose you either design your own with standard logic components or
license an existing a design.  I believe there is one processor design
with some sort of free licensing.

I added comp.arch.fpga to the group list.  This should bring in some
more knowledgeable folk.
