ROUGH SET METHODS AND HARDWARE IMPLEMENTATIONS
Maciej Kopczyński, Jarosław Stepaniuk · 2011
This paper describes current achievements about hardware realisation of rough sets algorithms in FPGA (Field Programmable Gate Array) logic devices. At the moment only few ideas and hardware implementations have been created. Most of the existing rough set methods implementations are software type. Software solution provides flexibility in terms of data processing and executed algorithms, but is relatively slow. Hardware imple- mentation limits this versatility, but gives a significant increase in calculation speed. The paper also includes brief description of current authors research on the creation of this type of implementation. The testing environment uses FPGA from Altera called Cyclone II. This is a high-capacity device providing the ability to create soft-processor core, along with modules allowing to support peripherals of the development board.
