  text: <jats:p>Intel recently introduced the Heterogeneous Architecture Research
    Platform, HARP. In this platform, the Central Processing Unit and a Field-Programmable
    Gate Array are connected through a high-bandwidth, low-latency interconnect and
    both share DRAM memory. For this platform, Open Computing Language (OpenCL), a
    High-Level Synthesis (HLS) language, is made available. By making use of HLS,
    a faster design cycle can be achieved compared to programming in a traditional
    hardware description language. This, however, comes at the cost of having less
    control over the hardware implementation. We will investigate how OpenCL can be
    applied to implement a real-time guided image filter on the HARP platform. In
    the first phase, the performance-critical parameters of the OpenCL programming
    model are defined using several specialized benchmarks. In a second phase, the
    guided image filter algorithm is implemented using the insights gained in the
    first phase. Both a floating-point and a fixed-point implementation were developed
    for this algorithm, based on a sliding window implementation. This resulted in
    a maximum floating-point performance of 135 GFLOPS, a maximum fixed-point performance
    of 430 GOPS and a throughput of HD color images at 74 frames per second.</jats:p>
