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. 1 Overview Reconfigurable logic is an emerging branch of computer architecture that seeks to build flexible computing systems that can achieve very high levels of performance --much higher performance than is possible with the highest performance microprocessors, or in many cases, even supercomputers. At the heart of these computing s...
