Increasing Design Functionality With Partial and Dynamic Reconfiguration in 28-nm FPGAs

Free registration required

Executive Summary

The density of FPGAs has grown with each process node shrink. Compared to previous generations of FPGAs, the extra density, coupled with features such as reconfiguration, enables designers to add to or change the functionality of these devices. FPGAs provide the perfect platform for accommodating improvements and design changes in functionality because of the reconfiguration feature. However, for some applications such as the 100G-Optical Transport Network (OTN) multiplexing transponders (muxponders), this full reconfiguration feature may not be good enough. Because the muxponder application requires changes in logic without disrupting the entire system and stopping the flow of data, a need for a partial reconfiguration feature comes into play.
