Abstract

A cache and TLB layout and design leverage repeater insertion to provide dynamic low-cost configurability trading off size and speed on a per application phase basis. A configuration management algorithm dynamically detects phase changes and reacts to an application's hit and miss intolerance in order to improve memory hierarchy performance while taking energy consumption into consideration.
