Wasn't "Crusoe", the CPU Linus Torvalds used to work on, a CPU core that could run multiple instruction sets?

In theory it seems you could be able to convert "on the fly" from multiple high level instruction sets to a singl low level microcode.

Not sure it's a good idea tho.

From what I remember at the time it never took off due to being expensive and having overly high power consumption. But perhaps it's an idea worth revisiting.
