ab: Summary: This paper presents a custom processor designed to execute a time
    consuming function in a CFD application. The selected function
    implements the method TDMA (Tri-Diagonal Matrix Algorithm) for solving
    a tri-diagonal system of equations. The custom processor was
    implemented in a commercial PCI prototyping board based on Virtex4LX
    FPGAs and uses a dedicated memory cache system, address generators and
    a deep pipelined floating-point datapath. Running at 100MHz and
    assuming the input data already in the cache memories, the system
    reaches a throughput greater than 1.4GFLOPS.
