You always want to eliminate some parts. But look at all the trade-offs we've been able to do on the x86 instruction side. We can do the same kinds of things on the system side. We don't do that yet. We'd just integrate everything we could onto the chip.
Integration is still a good idea.
Because it drives down power, assuming you use all the integrated parts, you don't have to drive electricity between chips. In all of this, the most interesting stuff is what we haven't done. We've been in this panic mode to get the basic instruction set working, without worring about the future too much. What I'd really like to have is that little unit we have as a mock-up. Yeah, that little one with the pieces.
