Dynamically reconfigurable system-on-programmable-chip

Abstract

Today's high-density FPGAs and intellectual property (IP) components enable the integration of complex systems in one programmable chip. New design strategies and concepts have to be developed in order to utilize the new system-level integration facilities. The approach introduced in this paper describes the implementation of a communication infrastructure that provides a number of on-chip IP-sockets. By using the FPGA feature of partial dynamic reconfiguration, different IP components can be plugged into these sockets at run-time. This leads to a reconfigurable system that can be adapted to varying demands. In this context, we designed a 32-bit RISC processor and an AMBA (Advanced Microcontroller Bus Architecture) on-chip interconnection bus. Finally, we mapped these components on to a reconfigurable system-level FPGA. The resulting hardware sizes and the utilization of the FPGA's resources are presented.
