Krakow (Poland), September 10-11, 2015.The FPGA-based accelerators and reconfigurable computer systems based on them require designing the applicationspecific processors soft-cores and are effective for certain classes of problems only, for which these soft-cores were previously developed. In Self-Configurable FPGA-based Computer Systems the challenge of designing the application-specific processors soft-cores is solved with use of the C2HDL tools, allowing them to be generated automatically. In this paper, we study the questions of the self-configurable computer systems efficiency increasing with use of the partially reconfigurable FPGAs and Chameleonc C2HDL design tool, corresponding to the goals of the project entitled "Improvement of heterogeneous systems efficiency using self-configurable FPGA-based computing" which is a part of the NESUS action. One of the features of the Chameleonc C2HDL design tool is its ability to generate a number of application-specific processors soft-cores executing the same algorithm that differ by the amount of FPGA resources required for their implementation. If the self-configurable computer systems are based on partially reconfigurable FPGAs, this feature allows them to acquire in every moment of its operation such a configuration that will provide an optimal use of its reconfigurable logic at a given level of hardware multitasking.8application/pdfengSelf-configurable computer systemsField-programmable gate arraysHigh-performance computingReconfigurable computingC2HDL design toolsconference paperInformáticaopen access135142Proceedings of the Second International Workshop on Sustainable Ultrascale Computing Systems (NESUS 2015): Krakow, Poland
