Part I consists of two extensive surveys FPGA and coarse-Grain reconfigurable architecture: FPGA technology is defined, which includes architectural, structural logic blocks, interconnect, and configuration methods and there are fine-grain reconfigurable architecture emerged from both academia and industry. In addition, implementation techniques and tools developed to facilitate the implementation of CAD systems in reconfigurable hardware provided by industry and academia. Besides the features, advantages and limitations of coarse-grain reconfigurable system, special issues to be addressed during the design phase, as well as representatives of existing coarse-grain reconfigurable systems are described. In Part II, case studies, the results of innovative research on reconfigurable architectures and design frameworks from three projects AMDREL, Molen and ADDRESS & DRESC, and, a new classification in accordance with the criteria described mikrokode architecture. Fine-and coarse-Grain reconfigurable computing is an essential reference for researchers and professionals and can be used as a textbook by scholars, students and lecturers.
