Optimizing FIR Filter Mapping on the Morphosys Reconfigurable System

Abstract

This paper proposes an optimized mapping of the FIR filter algorithm that enhances the rate of a reconfigurable computer over a basic mapping previously proposed [1]. It also presents a new interconnection scheme in the reconfigurable part of MorphoSys, a reconfigurable computing system [2]. Reconfigurable computing (RC) is introduced, followed by the MorphoSys RC system. Two optimized FIR mappings are then presented which deliver enhanced speed. A spreadsheet model will detail the modification and the improvement. The speedup achieved is also explained as well as the advantages in the mapping of the application.
