This paper provides an overview of the broad body-of-knowledge developed in the field of reconfigurable computing.ABSTRACT | Reconfigurable architectures can bring unique capabilities to computational tasks. They offer the performance and energy efficiency of hardware with the flexibility of software. In some domains, they are the only way to achieve the required, real-time performance without fabricating custom integrated circuits. Their functionality can be upgraded and repaired during their operational lifecycle and specialized to the particular instance of a task. We survey the field of reconfigurable computing, providing a guide to the body-ofknowledge accumulated in architecture, compute models, tools, run-time reconfiguration, and applications.
