Heterogeneous Multi-Processor Systems-on-Chip (MPSoC) exhibit increased design complexity due to numerous architectural parameters and hardware/software partitioning schemes. Automated Design Space Exploration (DSE) becomes an essential design procedure to discover optimized solutions in a reasonable time. For high-quality DSE, the accurate solution(More)
Modern multiprocessor heterogeneous systems incorporating multiple hardware accelerators on chip have resulted in an excessive increase in the complexity of hardware/software co-design. Designers have now to explore a design space including both per-accelerator architectural parameters as well as inter-accelerator combinations, i.e. different design(More)
As Multi-Processor Systems-on-Chip (MPSoC) architectures become more and more complex, Design Space Exploration (DSE) becomes the only viable solution for finding the pareto-optimal designs. To evaluate each solution with real dataset, DSE has to simulate the design under test, which is modeled as a Virtual Platform usually written in SystemC. However, the(More)
Due to the ever-increasing complexity of embedded system design and the need for rapid system evaluations in early design stages, the use of simulation models known as Virtual Platforms (VPs) has been of utmost importance as they enable system modeling at higher abstraction levels. Since a typical VP features multiple interdependent components, VP libraries(More)
Rician denoising is a mandatory task of Magnetic Resonance Imaging (MRI), as it enables higher-quality image processing, which is crucial for correct diagnosis. However, denoising is a slow task, especially because of the increased image resolution and the need for high image clarity. A solution towards this need is the implementation of rician denoise(More)
The scalability of communication infrastructure in modern Integrated Circuits (ICs) becomes a challenging issue, which might be a significant bottleneck if not carefully addressed. Towards this direction, the usage of Networks-on-Chip (NoC) is a preferred solution. In this work, we propose a software-supported framework for quantifying the efficiency of(More)
In the embedded system domain there is a continuous demand towards providing higher flexibility for application development. This trend strives for virtual prototyping solutions capable of performing fast system simulation. Among other benefits, such a solution supports concurrent hardware/software system design by enabling to start developing, testing, and(More)
Reconfigurable computing is a cost-effective alternative to technology shrinking in order to achieve higher performance in digital design, especially considering run time reconfiguration. Research in the field consists of new reconfigurable architectures, either coarse-grain or fine-grain, and new methodologies to map applications onto them. A special case(More)
The ever-growing design complexity of modern embedded systems and the need for lower energy consumption have lead to design techniques which target to bridge the gap between the designer's productivity and the design complexity. In particular, Virtual Prototyping enables the system modeling and simulation in multiple abstraction levels, while the automated(More)
