Taxonomy of Reconfigurable Computing and Operating System

Reconfigurable computing is a promising technology to meet future computational demand by leveraging flexibilities and the high degree of parallelism found in reconfigurable hardware fabrics, such as field programmable gate arrays (FPGAs) [1][2]. Reconfigurable computing had played an important role in the course of evolution of the computing paradigms. The journey of FPGAs had carried out from classical Von-Neumann Architecture to Reconfigurable Architecture. The concept of dynamic reconfiguration of the FPGA had been utilized properly with the flexibility of software programming and it has enabled the developers to map the computation intensive functions onto FPGAs. In this paper this journey of Hardware and Software has been described. Programmable hardware with programmable processors is combined in configurable computing systems to capitalize the strengths of hardware and software. This survey paper aims to introduce the research areas of last few years, to present a classification of reconfigurable architectures, and a brief illustration of reconfigurable operating systems [3] [4].
