Has anyone found or could recommend a small(ish) processor for more complex state machine tasks that is:
- ~1000 LUTs or so (smaller is better)
- available under a free license (say, GPL, LPGL, BSD)
- available in vhdl?
Ideally something like picoblaze would probably do what I want, except that it's not under any of the available licenses, and pacoblaze is vhdl (and potentially an IP nightmare). I've found a bunch of small processors on opencores and the like but many of them look half-finished. Any recommendations? These state machines are driving me mad!
