CHIP MORPHING
This seminar discusses results from the project called morph where the goal was to develop a micro architecture that can adapt it intrinsic performance dynamically. By observing the power dissipation, reducing the performance characteristics thus reduces the power even faster, resulting in greatly improved performance/ watt characteristics . these Techniques such as voltage scaling and as such add an extra time “gear” which real embedded system manipulate. In addition to the micro architecture work, the paper also briefly discuss the driving application to be used in its evaluation, namely planetary rovers and a discussion of some of the runtime software considerations that will be necessary to work through to make the “gear changing” a usable piece of technology. This paper has attempted to introduce the main concepts in the Morph project, an attempt to approach low power embedded system in a novel way - by attacking power consumption during those frequent times when less than peak performance is needed. The approach taken is that of adding an energy/performance “gear” - in such low performance demanding times, the intrinsic performance of the computer can be throttled back, and done so in ways where the energy per operation performed drops precipitously. The result should be a substantial improvement in the performance energy curve.
