By using ECL gate arrays, it is relatively easy to build processors that operate at 200 MHz (5 ns. clock) by 1990." (For those who don't know, Mr. Bell has his name on the PDP-11, the VAX, and the Ardent workstation.) The big iron is fighting back, and that involves reducing their chip count. Once, a big cpu took ~10^4 chips: now it's more like 10^2. I expect it will shortly be ~10 chips. Shorter paths, you know. I see the hot micros and the big iron meeting in the middle. What will distinguish their processors? Mainly, there will be cheap systems. And then, there will be expensive ones, with liquid cooling, superdense packaging, mongo buses, bad yield, all that stuff. Even when no multichip processors remain, there will still be $1K systems and $10M systems. Of course, there is no chance that the $10M system will be uniprocessor. -- Don D.C.Lindsay Carnegie Mellon Computer Science
