Virtualizing complex hardware, such as heterogeneous multiprocessor systems, enables developers to use standard Application Programming Interfaces (APIs) for application integration. Especially, the supply of an Operating System (OS) is well appreciated since many features such as drivers, the runtime environment and scheduling mechanisms are available and(More)
Efficiently managing the parallel execution of various application tasks onto a heterogeneous multi-core system consisting of a combination of processors and accelerators is a difficult task due to the complex system architecture. The management of reconfigurable multi-core systems which exploit dynamic and partial reconfiguration in order to, e.g. increase(More)
One challenge in developing complex software for embedded systems is the missing option of rapid prototyping in early stages of the development cycle. In this paper we present the use of the High Level Simulation Framework “Open Virtual Platforms” (OVP) for Software-in-the-Loop simulation of embedded control applications. Therefore, we(More)
The FlexTiles Platform has been developed within a Seventh Framework Programme project which is co-funded by the European Union with ten participants of five countries. It aims to create a self-adaptive heterogeneous many-core architecture which is able to dynamically manage load balancing, power consumption and faulty modules. Its focus is to make the(More)
The communication infrastructure is one of the important components of a multicore system along with the computing cores and memories. A good interconnect design plays a key role in improving the performance of such systems. In this paper, we introduce a hybrid communication infrastructure using both the standard bus and our area-efficient and(More)
Combination of reverse transcription (RT) and deep sequencing has emerged as a powerful instrument for the detection of RNA modifications, a field that has seen a recent surge in activity because of its importance in gene regulation. Recent studies yielded high-resolution RT signatures of modified ribonucleotides relying on both sequence-dependent mismatch(More)
Low-dimensional nanostructures offer a host of intriguing properties which are distinct from those of the bulk material, owing to size-confinement effects and amplified surface areas. Here, we report on the scalable, bottom-up synthesis of ultrathin coordination polymer nanosheets via surfactant-mediated synthesis and subsequent exfoliation. Layers of a(More)
Heterogeneous dynamic computing platforms are one of the big trends in today's electronic world. These platforms typically feature different General-Purpose-Processors (GPP) combined with accelerators on a reconfigurable layer. However, this necessitates specialized programming models and an Operating System (OS) for dealing with the dynamicity. To allow(More)
This paper presents a virtualization approach for heterogeneous adaptive multi-core systems distributed onto several FPGA-boards. The virtualization layer consists of an adapted embedded Linux kernel and several special purpose operating systems. The benefits are demonstrated with a complex image processing application.
