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 level to develop run-time reconfigurable systems. We present operating system extensions which enable seamless integration of run-time reconfigurable hardware threads into applications. To improve resource utilization, the hardware threads are placed on a fine granularity tile grid. We take advantage of a relocatable module placer targeting modern FPGA to manage the reconfigurable area. The module placer accurately models the FPGA resources to compute feasible placement locations for the hardware threads at run-time. Finally, we evaluate our work by means of a case study that consists of a synthetic application to validate the functionality and performance of the implementation. The results show a reduction in reconfiguration time of up to 42% and more than double resource utilization. https://ris.uni-paderborn.de/download/374/1400/374-2014_wold_arc.pdf application/pdf 2014 10.1007/978-3-319-05960-0_6 61-72 Wold, A., Agne, A., &#38; Torresen, J.
