Soft Processor Core

Just back from an practical "hands-on" seminar on Microblaze.
Didn't try that during the lab session, but was said that a reference design 
exists for a Spartan 3-50 fit (just 2 slices free!).
Obviously it's very limited, but it works. Something  like 766 slices... 
they said it can be really routed.

In my opinion, Mb excels when you need also some hardware co-processing 
functions made by surrounding FPGA logic, so you need some more free space, 
beside the core.
