Abstract

Achieving high speed run-time reconfiguration is important for the adaptation of partial reconfiguration in many applications. The reconfiguration speed that is currently available today is somehow artificially limited by the FPGA vendors, while the fabrication process technologies used for building the latest devices today are capable of achieving much higher reconfiguration speed. In this paper we will present a new design and implementation method for achieving high speed partial run-time reconfiguration that exceeds the specified reconfiguration speed of today's FPGAs. By adding custom logic around the Internal Configuration Access Port (ICAP) to implement an enhanced ICAP hard macro, we will investigate the partial run-time reconfiguration speed and explore the limits of the ICAP interface. This is done by using over clocking of the ICAP. Compared with previously work on high-speed reconfiguration, using the enhanced ICAP hard macro will significantly increase the reconfiguration speed.
