Talk Title: Future CPU Architectures: the Shift from Traditional Models

Talk Abstract:
While Moore''s law is alive and well in silicon scal

ing technology
it is clear that microprocessors have encountered signi

ficant technical issues that will influence the overall direction of the fu

ture architectures. This talk discusses the recent history of Intel microp

rocessors some of the rational that guided the development of those proces

sors. Further the talk highlights why the future microprocessor architectu

res will likely look different from the past.

The traditional microp

rocessor architecture uses hardware
techniques such as out-of-order pro

cessing to extract higher performance out of applications that have little

or no explicit parallelism. The hardware techniques employed in the past ha

ve continued to improve performance but at the cost of significantly
i

ncreasing the power consumption of the traditional microprocessors.
The
power increases have led to not only higher electrical power delivery cost

s but higher costs dissipating the power resulting in high ambient noise
larger enclosure and hotter laps. To avoid a future that requires asbestos
based jeans to properly handle laptops the microprocessor architecture mu

st change to facilitate higher performance without significantly higher pow

er.

It is likely that microprocessor architecture will evolve
fr

om the ubiquitous single core single threaded machine that we know and lov

e to an architecture that employs more cores and more threads. This shift

is apparent in today''s market where general purpose processors have includ

ed techniques such as Hyper-Threading Technology and Multi-Core processors.
This talk will speculate on some potential next steps for that technology

and some of the potential implications on software development.

ker Bio:
Doug Carmean is a Principal Architect with Intel''s Desktop
Products Group in Oregon. Doug was one of the key architects responsible

for definition of the Intel Pentium 4 processor. He has been with Intel for
13 years working on IA-32 processors from the 80486 to the Intel Pentium

4 processor and beyond. Prior to
joining Intel Doug worked at ROSS Tec

hnology Sun Microsystems
Cypress Semiconductor and Lattice Semiconduc

tor. Doug enjoys fast
cars and scary Italian motorcycles.
