Abstract

Field programmable gate arrays (FPGAs) provide an attractive solution to developers needing custom logic for short time-to-market products. Products embedding FPGA system-on-chip solutions have the advantage in that they can be updated once deployed. New FPGA firmware may be loaded via manufacturer-supplied memory devices or remotely via a network connection. Recent FPGAs allow for self-reconfiguration, where the user-FPGA fabric caninternally modify its own configuration data. Using selfreconfiguration, configuration control protocols can be implemented in user logic. This allows new FPGA programming methods to be designed. We propose a versatile partial self-reconfiguration framework for FPGA field updates that customizes to specific applications, reduces reconfiguration times, and minimizes the need for external hardware. The framework provides flexibility in media sources and design security. A prototype using this framework is demonstrated on a Xilinx Virtex-II FPGA.
