This paper describes an early power estimation method for Electronic System Level(ESL) design, which provides a scalable API to support automated power profiling and analysis at the early stages of the design process. The proposed framework utilizes a high-level power modeling mechanism along with an automated profiler to extract energy activity from the simulated system model. These two features...
This paper presents our performance profiling and the optimizations made to the program presented in the MEMOCODE SW design contest to make it faster when running in the Raspberry-Pi platform.
Nowadays, a lot of attention in the smart grids' development is devoted to methods of estimation of the energy demand by taking into account the behavior of network participants (single prosumers and groups). However, these methods take an advantage from an analysis of the ex-post data, and as such they use mainly the data covering the energy consumption with no additional information about prosumers...
This paper describes a model-based energy profiler for Android applications that allows developers to test the energy-efficiency of their applications in real user environments. The profiler offers analysis of the energy consumption using a system-wide power model generated for each type of device. The model, generated by regression analysis, can determine the relationship between power consumption...
MapReduce has become popular and Reduce-side join is one of the most important application of MapReduce. Data skew, in which the data load assigned to each Reduce task fluctuates task by task, increases the MapReduce job completion time. This paper proposes a dynamic profiling and feedback framework that works on a MapReduce cluster. The framework allows programmers to build their own algorithm to...
Performance estimation is a key step in the development of an embedded system. Normally, the performance evaluation is performed using a simulator or a performance mathematical model of the target architecture. However, both these approaches are usually based on the knowledge of the architectural details of the target. In this paper we present a methodology for automatically building an analytical...
Verification and test issues raise the need for rapid prototyping of complex systems and especially hardware/software-systems. We tackle this problem by integration of hardware/software-codesign and prototyping. First we define the concept of the entire system architecture. This concept directs the hardware/software-partitioning process. Our prototyping environment reflects the architecture concept...
