Tasks scaling with Chameleon© C2HDL design tool in self-configurable Computer Systems based on partially reconfigurable FPGAs
(Publishing House of Lviv Polytechnic National University, 2016) Melnyk, Anatoliy; Melnyk, Viktor; Tsyhylyk, Liubomyr
The FPGA-based accelerators and reconfigurable computer systems based on them require designing the application-specific processor soft-cores and are effective for certain classes of problems only, for which application-specific processor soft-cores were previously developed. In Self-Configurable FPGA-based Computer Systems the problem of designing the application-specific processor 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 Chameleon© C2HDL design tool. One of the features of the Chameleon© C2HDL design tool is its ability to generate a number of applicationspecific processor 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.
