Microprocessor Power Use

COMPUTER SCIENCE DEPARTMENT COLLOQUIUM

SPEAKER: Antonio González, Director, Intel Barcelona Research Center

TOPIC: Software to the Rescue of Power

DATE: Monday, May 10

TIME: 1:00 p.m.

PLACE: Olsson Hall Room 009

Abstract:  Power has become the main limiting factor for the scalability of microprocessors.  This limit is different for different systems (e.g. servers, desktops, laptops, MIDs, etc.), but in all of them it is already constraining the computing capabilities of the microprocessor.

Moore’s law will continue to provide us with the capability to integrate more devices in the same area, but the benefit of this ever increasing power density is jeopardized by the difficulties to dissipate the increased power it requires.  This clearly indicates that innovative solutions to reduce power are needed to harness the benefits of Moore’s law in order to keep delivering an increased performance to the end user.

To address this challenge, in this talk we will explore an approach based on implement microprocessors based on hardware/software co-design.

The main advantages of this approach are dramatic reductions in power and area without compromising performance when compared with traditional approaches.  This approach has other important advantages in the areas of scalability, reliability, legacy code and prototyping of new techniques that will be discussed.
