Model-based rapid prototyping of multirate digital signal processing algorithms

In this paper we present a design methodology that can be used for rapid prototyping and implementation of multi-rate digital signal processing algorithms. We start from a verified Simulink model of a digital down convertor and then proceed through model refinement, code generation, block interface definition and synthesis steps for FPGA prototyping and implementation. At the end we report FPGA implementation results and compare these results with the results obtained from another model based design tool, namely HDL Coder.
