Implementation of a Barotropic Operator for Ocean Model Simulation using a Reconfigurable Machine

This paper presents and discusses implementation of a barotropic operator used in ocean model simulation called Parallel Ocean Program (POP) using SRC-6 MAP. While a lot of high-end reconfigurable machines on which users can implement applications with a programming language are now available, enough implementation experience has not been accumulated for practical applications. In this paper, several implementation techniques accompanied by modification on original application source code are empirically evaluated and analyzed. The results show that appropriate use of internal memory and streaming DMA make 100 MHz FPGAs achieve comparative performance with GHz processors by using 100 MHz FPGAs.
