Reed-solomon behavioral virtual component for communication systems

Overview & Synopsis

In this paper, we focus on the design of a communication system based on reusing IP cores. We consider that traditional methods for hardware design at the RT level suffer from heavy limitations that prevent them from efficiently addressing the algorithmic complexity and the high flexibility required by the various application profiles. We propose to raise the abstraction level of the specification and introduce the notion of architectural flexibility of an IP core by benefiting from the emerging high-level synthesis tools. Our method has been successfully applied to the design of a Reed-Solomon (RS) decoder IP core, targeting the DVB-DSNG digital video broadcasting standard. We are able to generate a variety of RS decoder architectures, with varying hardware complexity and computation speed, from a single behavioral-level VHDL specification.
