TEAPC: Adaptive Computing and Underclocking in a Real PC

TEAPC is an IBM/Intel-standard PC realization of the TEAtime performance “maximizing” adaptive computing algorithm, giving performance beyond worstcase-specifications. TEAPC goes beyond the TEAtime algorithm by adapting to the current CPU load. It is also the first machine to use extensive underclocking for disaster tolerance, low power consumption and high reliability. This is all done dynamically, at runtime, on an unmodified standard operating system (Windows 2000) with a purely software-implemented feedback-control based algorithm. Copyright © 2004 A. K.
