OK, I'll bite. You're kidding, right ?

The only OpenRISC I know of is the OpenRISC 1200 from opencores.org,
and the available design is about 1M transistors (about the size of a 80486
IIRC), and the only actual mention of a part I've seen mentioned anywhere
had a target frequency of about 300 MHz. Dunno if it was ever built. My
memory may bit a bit fuzzy so YMMV.

Believe me, that kind of CPU power won't do h264 decoding in real-time...

... of course if you know of a supplier of parts based on that design (no
matter the actual performances), please let us know.
