Reconfigurable computing architecture survey and introduction

Reconfigurable computing has been driven largely by the development of commodity field-programmable gate arrays (FPGAs). Standard FPGAs are somewhat of a mixed blessing for this field.In this survey we give a brief overview of programming logics and we present configurable logic block (CLB) and look up table (LUT) as logic elements. Also we presented the definition of fine and coarse-grain architectures and present some commercial examples.This survey is also introduced the reconfigurable computing models like static and dynamic, single and multi-context and partial reconfiguration architectures. Finally run-time reconfigurable computing and the coupling of reconfigurable processing unit (RUP) delineated.
