I think this is new to me - a mention of a CPU which runs P-code directly.





(And of the course the mentioned P-code machine)

I was once in a conversation about making a BCPL machine, but some of the primitives are not at all primitive, and it didn't go anywhere.

Looks like an interesting (but rarely-updated) blog - subscribed!

That's very interesting, thanks for the link!
I used UCSD Pascal back in the eighties (with an Apple II), UCSD Pascal had a lot in common with Turbo Pascal (or rather, Turbo Pascal had copied concepts from the earlier UCSD Pascal), so the transition to CP/M and Turbo Pascal was easy. The reason for moving? Speed. The P-code interpreter wasn't very fast.
But I have looked into UCSD Pascal and P-code recently, trying to get an emulation of my old eighties setup running. And I wanted to write a P-code interpreter for my Linux box, but documentation is a bit sparse.
In any case, that WD900 is interesting. And of course, the idea of a P-code CPU in an FPGA follows. I imagine someone else must have had that idea already, so I'm sure there are many such implementations - but I haven't asked a search engine yet.
