In this paper we present a rapid-prototyping environment forfunctional verification and test of digital signal processing algorithms. The environment consists of a virrex-11 device on a PCI-card and an appropriate generic software backend which is used to pre-and post-process the data and to transfer it to the FPGA and pull the resultsfram it. It is designed to meet real-time requirements by means of interleaving block-transfers to andfrom a large on-board memory. We use the system for the development and test of audio signal processing applications. The implemenration and test of the gammatone-resynthesis algorithm is described as an exemplar) algorithm that has been tested within the environment. The presented system is part of a sofware framework for rapid development of power optimized audio signal processing applications on behavioral level using library elements.
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.
