Complexity Adaptive Processing

 

Description

The overall objective of the Complexity-Adaptive Processing (CAP) project is to provide on-the-fly, low-cost hardware adaptation so as to better match hardware complexity and speed to application demands, thereby dramatically improving power efficiency without unduly compromising performance. The specific goal is to demonstrate a one to two order of magnitude improvement in the energy-delay product of both embedded and high performance microprocessors. This goal will be achieved via hardware/software feedback and control mechanisms that characterize application behavior on-the-fly and correspondingly adjust hardware parameters (hardware complexity, latency, clock frequency, and supply voltage) to meet performance and power dissipation objectives, through the development of complexity-effective alternatives to complex hardware structures, and through additional innovations at the circuit and software levels.
