Implementation of finite difference schemes for the wave equation on FPGA

The computational requirements of finite difference schemes for the solution of the wave equation for physical modelling can be huge. Field programmable gate arrays (FPGAs) provide an ideal platform for performing highly parallel DSP computations, but the challenge is to be able to implement complex systems quickly and efficiently on FPGA platforms. The paper presents a system level design approach based on a dataflow model of computation using a particular finite difference scheme for the solution of a 2+1D wave equation. The results suggest that 84000 nodes could be accommodated on a single Virtex II FPGA.
