Power Everywhere,
too MUCH power,
and how the former prevents the later

What Constitutes Processor Technology?
► Circa
1960-2003
 Semiconductor Technology
– Materials, Devices (Ghz.), and the resultant Integrated
Circuits.

The Basics of Microprocessor
Technology; Think Small

►
Smaller transistors are faster
Smaller transistors are cheaper
Smaller transistors use less power
Smaller transistors can be packed more densely
Smaller transistors had remarkably predictable properties
Smaller transistors have enabled this industry for the past
4 decades
A Simple Question:
As things shrink, what happens when a transistor’s layers
approach the same size as what they’re made of, e.g. atoms?

We get to witness a historic
discontinuity in technology

Suggestions you don’t want to hear as Chief Technologist
 “Let’s make that transistor’s gate oxide layer 9.5 versus
10.0 angstroms”
Why?
 Atoms in that layer are a lot bigger than the 0.5 angstrom
being debated
Images you don’t want to see as Chief Technologist
Why?
 When one atom high
“bumps” look significant
in a photo of your transistors,
both their manufacture and
behavior will be “exciting”

Reasons why one must
rethink past strategies
►
Further technology shrinks produce seemingly bizarre
behaviors
 Transistors use the same power doing nothing as when they work
 It takes a week on a supercomputer to calculate the shape you
need to shine light on in order to get a rectangular shadow behind
it (Hint: It is not a rectangle when things get this small)
 Your new generation of transistors consume dramatically more
power than prior experience would have predicted
 Performance gains are slower than past experience would have
indicated

This is the “good” news

What Constitutes Processor Technology?
► Circa
2004-2044
 Materials, Devices, Scalable and Integrable Cores (IP),
System Architecture, System Integration, and System
Software
– The word “Technology” now encompasses far more than just
semiconductors going into the future
– Integration, the creation of systems rather than just “chips”,
will become the means by which past trajectories for
computing performance are maintained
● It takes a vibrant processor ecosystem to enable this

Semiconductors now rely on
innovation vs. “shrinks”

Holistic Design; Atoms to
Software, A New Imperative
►
Only the simultaneous optimization of materials, devices,
circuits, cores, chips, system architecture, and system
software, provides an effective means to optimize for both
performance and power.
►
Power Architecture is taking a major step towards creating
an open ecosystem of highly scalable cores having power
control and performance characteristics required for future
Processor Technology.
 Asset virtualization
 Fine grained clock gating
 Dynamically optimized multi-threading capability
 Open (accessible) architecture for system optimization/compatibility
 Scalability enabling IP re-use in a broad range of systems and
products

Where will this take us in
the coming decade?
► An
IP Marketplace to facilitate system Integration
 An “Open Source” model enabling System-On-Chip
assembly
► Technology
that is itself adaptive to system needs
 Smart systems interacting with base technology to drive
dynamic optimization, self-repair, and long term
upgrades.
– The chip you have may not be the chip you bought
► Integration
eclipses Ghz
 Consumers continue to see dramatic improvements in
product functionality as the IP ecosystem blossoms
