Implementation approaches for reconfigurable logic applications

Abstract

Reconfigurable FPGAs provide designers with new implementation approaches for designing high-performance applications. This paper discusses two basic implementation approaches with FPGAs: compiletime reconfiguration and run-time reconfiguration. Compile-time reconfiguration is a static implementation strategy where each application consists of one configuration. Run-time reconfiguration is a dynamic implementation strategy where each application consists of multiple cooperating configurations. This paper introduces these strategies and discusses the implementation approaches for each strategy. Existing applications for each strategy are also discussed.
