Special Issue Information

Embedded computing permeates our daily life in different forms, from electronic devices at our homes to mobile devices such as smartphones. Most computing devices in embedded systems impose strict constraints that require special development and design efforts. Reducing power dissipation and/or energy consumption is in many cases needed to obey those constraints and contribute to the success of many embedded systems. This Special Issue will be devoted to recent research achievements regarding energy-efficient software and hardware techniques for embedded computing. Specifically, articles about the following topics, all addressing embedded computing, are welcome:

  • Software-based optimizations for saving energy consumption;
  • Hardware-based optimizations for saving energy consumption;
  • Trade-offs between QoS/QoE and energy consumption;
  • Optimizing for power dissipation and energy consumption;
  • Runtime autotuning techniques for energy efficiency;
  • Runtime adaptability for energy efficiency;
  • Impact of data structures and types on energy efficiency;
  • Educational approaches regarding energy efficiency;
  • Best software/hardware practices for energy efficiency;
  • AI for energy-efficient software/hardware systems;
  • Energy-efficient computing using emerging non-volatile memory technologies;
  • Energy-efficient in-memory or near-memory computing.

Optimizing software to become (more) energy efficient is an important concern for the software industry. Although several techniques have been proposed to measure energy consumption within software engineering, little work has specifically addressed Software Product Lines (SPLs). SPLs are a widely used software development approach, where the core concept is to study the systematic development of products that can be deployed in a variable way, e.g., to include different features for different clients. The traditional approach for measuring energy consumption in SPLs is to generate and individually measure all products, which, given their large number, is impractical. We present a technique, implemented in a tool, to statically estimate the worst-case energy consumption for SPLs. The goal is to reason about energy consumption in all products of a SPL, without having to individually analyze each product. Our technique combines static analysis and worst-case prediction with energy consumption analysis, in order to analyze products in a feature-sensitive manner: a feature that is used in several products is analyzed only once, while the energy consumption is estimated once per product. This paper describes not only our previous work on worst-case prediction, for comprehensibility, but also a significant extension of such work. This extension has been realized in two different axis: firstly, we incorporated in our methodology a simulated annealing algorithm to improve our worst-case energy consumption estimation. Secondly, we evaluated our new approach in four real-world SPLs, containing a total of 99 software products. Our new results show that our technique is able to estimate the worst-case energy consumption with a mean error percentage of 17.3% and standard deviation of 11.2%. Full article
