  text: '<jats:p> Field-Programmable Gate Arrays (FPGAs) are widely used in the central
    signal processing design of the Square Kilometer Array (SKA) as hardware accelerators.
    The frequency domain acceleration search (FDAS) module is an important part of
    the SKA1-MID pulsar search engine. To develop for a yet to be finalized hardware,
    for cross-discipline interoperability and to achieve fast prototyping, OpenCL
    as a high-level FPGA synthesis approaches employed to create the sub-modules of
    FDAS. The FT convolution and the harmonic-summing plus some other minor sub-modules
    are elements in the FDAS module that have been well-optimized separately before.
    In this paper, we explore the design space of combining well-optimized designs,
    dealing with the ensuing need to trade-off and compromise. Pipeline computing
    is employed to handle multiple input arrays at high speed. The hardware target
    is to employ multiple high-end FPGAs to process the combined FDAS module. The
    results show interesting consequences, where the best individual solutions are
    not necessarily the best solutions for the speed of a pipeline where FPGA resources
    and memory bandwidth need to be shared. By proposing multiple buffering techniques
    to the pipeline, the combined FDAS module can achieve up to 2[Formula: see text]
    speedup over implementations without pipeline computing. We perform an extensive
    experimental evaluation on multiple high-end FPGA cards hosted in a workstation
    and compare to a technology comparable mid-range GPU. </jats:p>'
