Monster Chip like Monster Home?
“…what San Franciscans have come to know as a monster home--a 6,000- square-foot behemoth that would tower five stories high, casting neighbors in its shadow and stretching clear to its lot lines.”
“San Franciscans Fight Monster Home Invasion,” LA Times, 7/13/00
Bay Area cities using ordinances to stop them
Era of wretched excess: home,PC
Memory for branch prediction bigger than minicomputer memory!
Word processors that need 16 MB!

2. Desktop vs. Gadgets/Server

Desktop vs. Gadgets/Server
Desktop has warped design space: max die size, max SPEC, power be damned
Gadgets: Cost/Power/Performance
MIPS per joule, MIPS per dollar
2001: 500 – 550 million cell phone handsets, each with 32-bit MPU + DSP vs. 120 million PCs
Servers: Power/Throughput
Tasks per second v. SPECmark
Future: low power so combined with disks

Sustaining Moore’s Law vs. MIPS/$?
Intel MPU die
~1000X
RISC II die
Scaled 32-bit, 5-stage RISC II 1/1000th of current MPU, die size or transistors

New view: ClusterOnaChip (CoC)
Inspiration: Google
Search engine for world: 100M/day
Economical, scalable build block:PC cluster today 6000 PCs, disks
Advantages in fault tolerance, scalability, cost/performance
32-bit MPU as the new Nand Gate
“Cluster on a chip” with 100s of MPUs enable amazing MIPS/$, MIPS/watt for cluster applications
MPUs combined with dense memory + system on a chip CAD + quick turn fab
30 years ago Intel 4004 used 800 gates: when 800 MPU chip?
