—Modern compute systems continue to evolve towards increasingly complex, heterogeneous and distributed architec-tures. At the same time, functionality and performance are no longer the only aspects when developing applications for such systems, and additional concerns such as flexibility, power efficiency, resource usage, reliability and cost are becoming(More)
—In the next decades, hybrid multi-cores will be the predominant architecture for reconfigurable FPGA-based systems. Temperature-aware thread mapping strategies are key for providing dependability in such systems. These strategies rely on measuring the temperature distribution and predicting the thermal behavior of the system when there are changes to the(More)
While numerous publications have presented ring oscil-lator designs for temperature measurements a detailed study of the ring oscillator's design space is still missing. In this work, we introduce metrics for comparing the performance and area efficiency of ring oscillators and a methodology for determining these metrics. As a result, we present a(More)
—With the introduction of multithreaded programming for reconfigurable hardware, it is possible to map both sequential software and parallel hardware to a single CPU/FPGA platform using threads as a unifying development model. At the same time, platform FPGAs are a natural technology for implementing computationally intensive systems in the aerospace,(More)
—Due to the continuously shrinking device structures and increasing densities of FPGAs, thermal aspects have become the new focus for many research projects over the last years. Most researchers rely on temperature simulations to evaluate their novel thermal management techniques. However, the accuracy of the simulations is to some extent questionable and(More)
―The ReconOS operating system for reconfigurable computing offers a unified multi-threaded programming model and operating system services for threads executing in software and threads mapped to reconfigurable hardware. The operating system interface allows hardware threads to interact with software threads using well-known mechanisms such as semaphores,(More)
Self-aware computing is a paradigm for structuring and simplifying the design and operation of computing systems that face unprecedented levels of system dynamics and thus require novel forms of adaptivity. The generality of the paradigm makes it applicable to many types of computing systems and, previously, researchers started to introduce concepts of(More)
The ReconOS operating system provides a common, multithreaded model for programming multi-core processors that feature reconfig-urable hardware cores as well as general instruction set cores. A paradigm shift from single-core to parallel multi-core processors has occurred over the last couple of years to further increase the performance of processors.(More)
Run-time reconfiguration provides an opportunity to increase performance, reduce cost and improve energy efficiency in FPGA-based systems. However, run-time reconfigurable systems are more complex to implement than static only systems. This increases time to market, and introduces run-time overhead into the system. Our research aims to raise the abstraction(More)
