A dynamically tunable memory hierarchy

A Dynamically Tunable Memory Hierarchy

The widespread use of repeaters in long wires creates the possibility of dynamically sizing regular on-chip structures. We present a tunable cache and translation lookaside buffer (TLB) hierarchy that leverages repeater insertion to dynamically trade off size for speed and power consumption on a per-application phase basis using a novel configuration management algorithm. In comparison to a con...

Realisation of a Dynamically Grouped Object-Oriented Virtual Memory Hierarchy

Conventional paging systems do not perform well with large object-oriented environments (such as Smalltalk-80 [GR83]) due to the fine granularity of objects and the persistence of the object space. One approach taken to increase efficiency has been to group objects together in virtual space in an attempt to keep related objects on the same page. Conventionally, grouping has been performed whils...

Dual-band, Dynamically Tunable Plasmonic Metamaterial Absorbers Based on Graphene for Terahertz Frequencies

In this paper, a compact plasmonic metamaterial absorber for terahertz frequencies is proposed and simulated. The absorber is based on metamaterial graphene structures, and benefits from dynamically controllable properties of graphene. Through patterning graphene layers, plasmonic resonances are tailored to provide a dual band as well as an improved bandwidth absorption. Unit cell of the design...

Adaptive Tunable Vibration Absorber using Shape Memory Alloy

This study presents a new approach to control the nonlinear dynamics of an adaptive absorber using shape memory alloy (SMA) element. Shape memory alloys are classified as smart materials that can remember their original shape after deformation. Stress and temperature-induced phase transformations are two typical behaviors of shape memory alloys. Changing the stiffness associated with phase tran...
