Improving TLB Energy for Java Applications on JVM

Java platforms are widely deployed and used ranging from ultra-mobile embedded devices to servers for their portability and security. The TLB, a content addressable memory, can consume a significant power in these systems due to the nature of its associative search mechanism. This paper proposes and investigates three different optimizations for the TLB design, aiming to improve its power consumption for Java applications running on top of Java Virtual Machines. The techniques exploit unique memory reference characteristics demonstrated by the JVM and its interaction with the Java applications running atop.
