Soft-core processor construction

One where you never see the naughty bits...

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.
