Abstract

Reconfigurable architectures combine the high flexibility of general purpose processors with the high performance of specialized hardware architectures. They can be implemented on field programmable gate arrays or on custom coarse grain reconfigurable arrays (CGRA). Often the CGRAs are designed in a domain specific way. In this contribution, we present a mixture of both: a domain specific custom reconfigurable architecture implemented with the help of a particular feature of modern Virtex FPGAs (Virtex 5 and up). We show that our custom architecture joins the qualities of both alternatives: a full hardware implementation and a reconfigurable solution based on vendor tools. Our custom tool for the programming of the architecture performs considerably faster than using partial reconfiguration and the standard vendor tools and is smaller than a full hardware solution.
