Query: Combining Multiple Optimised FPGA-based Pulsar Search Modules Using
  OpenCL   Field-Programmable Gate Arrays (FPGAs) are widely used in the central signal
processing design of the Square Kilometre Array (SKA) as acceleration hardware.
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 finalised
hardware, for cross-discipline interoperability and to achieve fast
prototyping, OpenCL as a high-level FPGA synthesis approach is 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-optimised separately before. In this paper, we explore the design
space of combining well-optimised 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 2x speedup over implementations
without pipeline computing. We perform an extensive experimental evaluation on
multiple FPGA boards (Arria 10) hosted in a workstation and compare to a
technology comparable mid-range GPU.
