Power- and time-aware buffer cache management for real-time embedded databases

Buffer Cache Management for Low Power Consumption

As the computing environment moves to the wireless and handheld system, the power efficiency is getting more important. That is the case especially in the embedded hand-held system and the power consumed by the memory system takes the second largest portion in overall. To save energy consumed in the memory system we can utilize low power mode of SDRAM. In the case of RDRAM, nap mode consumes le...

A Power Aware Cache and Register File Design Space Exploration

Cache isolation for virtualization of mixed general-purpose and real-time systems

Shared cache has been widely used to lessen the communication overhead between multi-core processors and off-chipmainmemories. In a virtualization execution environment, real-time tasks supported by realtime operating systems (RTOS) need to share the last level cache with other general purpose tasks (supported by general purpose operating systems (GPOS) or execute on bare metal). Since current ...

TaPT: Temperature-Aware Dynamic Cache Optimization for Embedded Systems

Embedded systems have stringent design constraints, which has necessitated much prior research focus on optimizing energy consumption and/or performance. Since embedded systems typically have fewer cooling options, rising temperature, and thus temperature optimization, is an emergent concern. Most embedded systems only dissipate heat by passive convection, due to the absence of dedicated therma...

Dynamic Reconfiguration of Two-Level Cache Hierarchy in Real-Time Embedded Systems

System optimization techniques based on efficient dynamic reconfiguration have been widely adopted in recent years. Cache reconfiguration is a promising optimization technique for reducing memory hierarchy energy consumption with little or no impact on overall system performance. While cache reconfiguration is successful in desktop-based and embedded systems, it is not directly applicable in re...
