We introduce a novel dynamically reconfigurable 2D filterbank that is based on separable, one-dimensional filters. At the lowest level, each 2D filter is implemented using dynamic reconfiguration between two one-dimensional filters. Then, at a higher level, filterbanks are implemented using dynamic partial reconfiguration of efficient 1D filter blocks (based on distributed arithmetic). We have evaluated the system's overall performance as a function of the reconfiguration rate and we show that real-time video processing speeds for 2D video filtering can be attained for several image sizes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
