Temperature-Aware Runtime Power Management for Chip-Multiprocessors with 3-D Stacked Cache

The advent of 3-D fabrication technology makes it possible to stack a large amount of last-level cache memory onto a multi-core die to reduce off-chip memory accesses and, thus, increases system performance. However, the higher power density (i.e., power d ...

Parallel and Distributed Optimization of Dynamic Data Structures for Multimedia Embedded Systems

David Atienza Alonso, José Luis Risco Martin

Energy-efficient design of multimedia embedded systems demands optimizations in both hardware and software. Software optimization has no received much attention, although modern multimedia applications exhibit high resource utilization. In order to efficie ...

A Parallel Evolutionary Algorithm to Optimize Dynamic Memory Managers in Embedded Systems

David Atienza Alonso, José Luis Risco Martin

For the last 30 years, several dynamic memory managers (DMMs) have been proposed. Such DMMs include first fit, best fit, segregated fit and buddy systems. Since the performance, memory usage and energy consumption of each DMM differs, software engineers of ...

Mixed Heuristic and Mathematical Programming Using Reference Points for Dynamic Data Types Optimization in Multimedia Embedded Systems

David Atienza Alonso, José Luis Risco Martin

New multimedia embedded applications are becoming increasingly dynamic. Thus, they cannot only rely on static data allocation, and must employ Dynamically-allocated Data Types (DDTs) to store their data and efficiently use the limited physical resources of ...

Optimization of Dynamic Memory Managers for Embedded Systems Using Grammatical Evolution

David Atienza Alonso, José Luis Risco Martin

New portable consumer embedded devices must execute multimedia applications (e.g., 3D games, video players and signal processing software, etc.) that demand extensive memory accesses and memory usage at a low energy consumption. Moreover, they must heavily ...

Analysis of Multi-Objective Evolutionary Algorithms to Optimize Dynamic Data Types in Embedded Systems

David Atienza Alonso

New multimedia embedded applications are increasingly dynamic, and rely on Dynamically-allocated Data Types (DDTs) to store their data. The optimization of DDTs for each target embedded system is a time-consuming process due to the large design space of po ...
